There are an extensive number of extraterrestrial races known to be currently interacting with Earth and the human population. In a 1998 interview, Clifford Stone, a retired US army Sergeant who served in the US Army for 22 years and participated in covert operations to retrieve crashed extraterrestrial ships and extraterrestrial biological entities (EBE's), revealed there were a total of 57 extraterrestrial races known to the US military.  From this pool of extraterrestrial races, a number are more active than others, and can be claimed to have the most significance for human evolution and sovereignty. The extensive number of reports and testimonies concerning different extraterrestrial races indicates that the motivations and activities of extraterrestrial races vary greatly, and an idea of these motivations can be distilled from close examination of these reports and testimonies.
The most compelling testimonies on the different extraterrestrial races comes from 'whistleblowers' such as Sergeant Stone who served for long periods in the military and/or corporations participating in 'black projects'; and 'contactees' in a broad sense of those who have had direct physical contact with extraterrestrials and communicated with them. This includes both 'contactees' in the classic sense of those who have voluntarily interacted with extraterrestrial races, and 'abductees' who have been involuntarily incorporated into extraterrestrial programs.  I will first refer to some of the main sources of information for different extraterrestrial races generally operating on Earth, and then attempt to make specific descriptions about the motivations and activities of these races using available sources.
While there may be considerable debate over the accuracy of the information provided by the whistleblowers and contactees presented in this report, I have argued elsewhere that 'whistleblowers' and 'contactees' provide the strongest evidentiary sources for the extraterrestrial phenomenon.  What further helps in supporting the reliability of the information provided by these 'whistleblowers' and 'contactees' is the consistency and coherence of the testimonies and evidence provided by them, and ultimately the credibility of the individuals involved. Consequently, this report will focus primarily on the testimony on a select number of 'whistleblowers' and 'contactees' whose consistency, coherence and credibility suggest they are providing reliable information on the motivations and activities of different extraterrestrial races.
Master Sergeant Bob Dean had a twenty-seven year military career and at one time during his service worked in military intelligence at the Supreme Headquarters of the Allied Powers in Europe (SHAPE) from 1963. His distinguished service record gives him great credibility in claiming to have witnessed classified information during his military service. During his SHAPE assignment he claimed he was instructed to read a detailed study of the activities of UFOs/ETs and how they might impact on Soviet-NATO relations which was published in 1964 with the title: "An Assessment: An Evaluation of a Possible Military Threat to Allied Forces in Europe."  In an interview, Dean described four extraterrestrial races described in 'The Assessment' as follows:
The group at the time, there were just four that they knew of for certain and the Greys were one of those groups. There was a group that looked exactly like we do. There was a human group that looked so much like us that that really drove the admirals and the generals crazy because they determined that these people, and they had seen them repeatedly, they had had contact with them, there had been abductions, there had been contacts. These people looked so much like us they could sit next to you on a plane or in a restaurant and you'd never know the difference. And being military and being primarily paranoid, that bothered the generals and the admirals a little bit. That the fact that these intelligent entities could be involved with us, walking up and down the corridors of SHAPE, walking down the corridors of the Pentagon. My God, it even dawned on a couple of them that these guys could even be in the White House! Of course, as I said, being paranoid in those years it really shook things up a little bit.
Two other groups, there was a very large group, I say large, they were 6-8 maybe sometimes 9 feet tall and they were humanoid, but they were very pale, very white, didn't have any hair on their bodies at all. And then there was another group that had sort of a reptilian quality to them. We had encountered them; military people and police officers all over the world have run into these guys. They had vertical pupils in their eyes and their skin seemed to have a quality very much like what you find on the stomach of a lizard. So those were the four they knew of in 1964. But I've been told by friends that are still active in military service that it's well over a dozen by now. 
Those who are here to assist humanity ..
Outside of the Military-Industrial-Extraterrestrial Complex
On February 20, 1954, a delegation of 'human looking' extraterrestrial races met with the Eisenhower administration in an unsuccessful effort to reach an agreement on the US's thermonuclear nuclear weapons program.  The apparent stumbling block was that these extraterrestrial races were not willing to provide technology that might be used by the military-industrial interests that dominated the Eisenhower administration and set the tone for subsequent extraterrestrial - human dialogue. The principled opposition of this group of extraterrestrials to being co-opted into an emerging military-industrial-extraterrestrial complex (MIEC) marks an important indicator of a large grouping of 'human' extraterrestrial races who lie outside of the web of interlocking interests that make up the MIEC in the US and elsewhere on the planet.
This second group of extraterrestrials is primarily 'human' and can easily integrate with human society in the manner described by Dean and others where they can be indistinguishable from the rest of humanity.  These races are described to be from star systems such as Lyra, Pleiades, Sirius, Procyon, Tau Ceti, Ummo, Andromeda and Arcturus who have provided some of the genetic material for the seeding of humanity on Earth.  According to Alex Collier, a total of 22 extraterrestrial races have provided genetic material for the 'human experiment'. These include Reptilian, Gray and Anunnaki races described earlier as well as those races in this second group, which Collier describes as 'benevolent':
That we, as a product of extraterrestrial genetic manipulation, are possessors of a vast gene pool consisting of many different racial memory banks, also consisting of at least 22 different races. Because of our genetic heritage, and because we are spirit, the benevolent extraterrestrial races actually view us as being royalty. 
As a result of this genetic linkage, the extraterrestrials in this group outside of the MIEC apparently view humanity in much the way a protective parent might view an adolescent son/daughter in a dangerous environment.  The vital interests of races in this category are to ensure that global humanity evolves in a responsible way without endangering both itself and the greater galactic community of which it is part.
There are two parts to this grouping of extraterrestrials. The first are 'extraterrestrials' that have historically inhabited the Earth's subterranean dwellings, and are described as remnants of ancient human civilization that followed a separate evolutionary path to surface humanity. The second are extraterrestrials that have 'off-world' origins but have humanoid features to the extent that some of them can easily intermingle with the rest of humanity without being easily identified.
The subterranean 'extraterrestrials' are described to be remnants of previous human civilizations on the Earth's surface such as Lemuria and Atlantis and are thus genetically related to humanity. The most famous description of one of these ancient races is found in the posthumously published 'diaries' of Admiral Richard Byrd who describes a secret expedition to the North Pole where he was taken into the subterranean dwelling of an advanced race with Nordic physical characteristics. He was shown some of the wondrous technology of this society and also met the leader of this advanced subterranean race who allegedly said:
'We have let you enter here because you are of noble character and well-known on the Surface World, Admiral' you are in the domain of the Arianni, the Inner World of the Earth . Admiral, I shall tell you why you have been summoned here. Our interest rightly begins just after your race exploded the first atomic bombs over Hiroshima and Nagasaki, Japan. It was at that alarming time we sent our flying machines, the "Flugelrads", to your surface world to investigate what your race had done . You see, we have never interfered before in your race's wars, and barbarity, but now we must, for you have learned to tamper with a certain power that is not for man, namely, that of atomic energy. Our emissaries have already delivered messages to the powers of your world, and yet they do not heed. Now you have been chosen to be witness here that our world does exist. You see, our Culture and Science is many thousands of years beyond your race, Admiral.' 
While there continues to be controversy over the veracity of Admiral Byrd's diaries, there are a number of reported encounters with representatives of an advanced subterranean human race. A large subterranean city called Telos is argued to lie below Mt Shasta, California and has been described by individuals who have either physically traveled to this city and witnessed it, or those who claim to have telepathically communicated with the occupants of this city. Prominent UFO researcher, William Hamilton, claims to have met representatives of Telos who described to him the advanced technology and structure of Telos and their connection to the former civilization of Lemuria.
The 'off-world' human looking extraterrestrial have been claimed to have provided some of the genetic material for human evolution, and that many of these extraterrestrials have allowed some of their personnel to incarnate as 'star seeds' on Earth in human families. These 'star seeds', 'star children' or 'star people' are described by Brad and Francie Steiger as individuals whose 'souls' were formally incarnated on the worlds of other star systems and then traveled to Earth and decided to incarnate here in order to boost the evolutionary development of humanity.  Most of humanity would consider this group of extraterrestrials to be 'benevolent' as described by 'contactees' such as George Adamski, Orfeo Angelucci, George Van Tassell, Howard Menger, Paul Villa, Billy Meier and Alex Collier who each explain the nature of their voluntary interactions with these human looking extraterrestrials.  These contactees often provide physical evidence in the form of photographs, film and/or witnesses of their contacts with extraterrestrial races. The most extensively documented and researched contactee is Eduard 'Billy' Meier who provided much physical evidence for investigators. These off world human extraterrestrial races appear to have different 'specialties' as a result of unique histories and planetary migrations due to galactic upheavals and conflicts. It is worth exploring the main activities of each race to understand how they either currently interact with humanity or how they may better interact with humanity to address global problems.
It is appropriate to begin the discussion of these 'off world' extraterrestrial races and their main activities by focusing on a star system that has been described as the source for the spread of human civilization in the Milky War galaxy, the constellation of Lyra. One of the first 'contactees' to describe Lyra was Billy Meier who received much public attention as a result of his alleged visits from Pleiadians/Plejarans from 1975 to 1986, which he supported with material evidence that continues to confound those skeptical of Meier's claims. 
Comprehensive investigations by a number of individuals and organizations found that Meier's evidence was not fabricated and therefore constituted significant support for his testimony of extraterrestrial contact.  Due to the amount of physical evidence he had provided over the years, Meier has gained great credibility, and the consistency and coherence of his testimonies suggest that he is indeed an important spokesperson for an extraterrestrial race.
Meier was told by his Pleiadians [Plejadians] contacts of the star system of Lyra and its human inhabitants:
The "Swiss" Plejadians have described their ancient ancestry, and consequently ours, as originating (before the Plejades) in a far sun-system in a star group near what we now know as the Ring Nebula of Lyra, for which we have called them Lyrians in the same manner as we refer to the human beings from what we call the Pleiades. These early Lyrians in their numerous migrations in their great Space Arks went to many other star systems and found suitable habitations, and put down colonies, such of which flourished and eventually launched their own space travelers. 
Those ET's from Andromeda are also described by Alex Collier as having been direct descendents of the Lyrans who experienced some difficulty when first leaving the Lyran system due to predatory extraterrestrial races, but eventually settled in the Andromeda constellation in the star system 'Zenetae'. Collier describes the nature of the Andromedans as follows:
Everything that they create technologically is used for the advancement of their race. It is for educational purposes only. But, it can be used in defense. No, they do not have a military, per se, they are scientists. What they do is send their children to school anywhere from 150 to 200 years, in our linear time. They teach their students all of the arts and sciences. They are literally masters at everything. Then, at that point, they have the choice in what it is they want to do, and they can change their minds anytime and do something else. So, they are given all the tools. Everything is for education. Nothing is for distraction. They would never conceive of creating television as a distraction. Never. Everything is to help them evolve, and their science and their technology can be used for defensive purposes -- mostly the holographic stuff. 
The most significant feature of the Andromedans is that they are instrumental in the Andromeda Council, which is a grouping of approximately 140 star systems who deliberate upon Earth. In a 1997 Interview, Collier described the Council's deliberations as follows:
Now, in our galaxy there are many councils. I don't know everything about all those councils, but I do know about the Andromedan council, which is a group of beings from 139 different star systems that come together and discuss what is going on in the galaxy. It is not a political body. What they have been recently discussing is the tyranny in our future, 357 years from now, because that affects everybody. Apparently what they have done, through time travel, is that they have been able to figure out where the significant shift in energy occurred that causes the tyranny 357 years in our future. They have traced it back to our solar system, and they have been able to further track it down to Earth, Earths moon and Mars. Those three places. The very first meeting the Andromedan council had was to decide whether or not to directly intervene with what was going on here. According to Moraney, there were only 78 systems that met this first time. Of those 78, just short of half decided that they wanted nothing to do with us at all, regardless of the problems. I think it is really important that you know why they wanted nothing to do with us. We are talking about star systems that are hundreds of millions of light years away from us. Even some who have never met us. They just knew the vibration of the planet reflected those on it. The reasons why they wanted nothing to do with us is that from their perspective, Earth humans don't respect themselves, each other or the planet. What possibly can be the value of Earth humans? Fortunately, the majority of the council gave the opinion that because Earth has been manipulated for over 5,700 years, that we deserved an opportunity to prove ourselves - to at least have a shot at proving the other part of the council wrong. 
The Andromedans' chief activity appears to be facilitating decisions of the Galactic community in dealing with difficult problems such as the current Earth situation, innovative strategies for resolving conflict, and the education of youth. The global solutions they promote include assisting the growth of psychic/crystal/rainbow children, peace education, exposing elite manipulation, promoting improved global governance, and diplomacy and conflict resolution.
The Ummites are described as extraterrestrials from the planet Ummo which is claimed to be 14.6 light years away, and possibly located in the star system Wolf 424.  They played a significant role in disseminating scientific technical literature and objects through Spain and then relayed to the rest of Europe in the 1960s and 1970s from a hidden base near a small town in the French province of 'Basses Alps' (Lower Alps). The Ummites contacted a select number of individuals and distributed to them detailed technical information on different technologies and revolutionary theories that would expand scientific knowledge beyond the prevailing orthodoxies. The only physical contact the Ummites had with anybody, aside from phone calls and sending technical information by regular mail, was with a hired typist who described how he worked for and eventually discovered the identities of the Ummites:
Between 1967 and 1975 the members of the Madrid group [Spanish UFO researchers aware of the Ummites] received a letter from a man who claimed to be the Ummites' typist. Apparently, he had advertised for work in a newspaper and had subsequently been visited by two tall, fair-haired respectable dressed men. They told him that they were Danish doctors and asked if he could type out scientific material for them on a regular basis. Initially all went well, until the day he read the following sentence: 'We come from a celestial body named Ummo, which is 14.6 light years from the Earth. - He took this at its face value and questioned the doctors - eventually they admitted that they were not Danish doctors at all, but extra-terrestrial visitors. To prove their identity they produced a tiny sphere just an inch or so in diameter, which one of them placed in mid-air before the typist. He looked into it and to his amazement saw a scene that had taken place in that same office on the preceding day when his wife, fearing that the Danish doctors might be spies. 
There was however a well-recorded public event in the form of an Ummo spacecraft that landed near Madrid on June 10, 1967 that was announced by the Ummites several days before to a select group of UFO researchers.  The Ummite's approach appears to be one of helping scientists develop innovative technologies and theories that assist in addressing global problems that require technical solutions. In 1973, due to the uncertainty over a nuclear war on Earth, the Ummites terminated their residence on Earth and departed. They subsequently sent the following message in 1980 to Dr Antonio Ribera, one of the Spanish UFO researchers that had taken up their case:
For 30 years we have studied your science, your culture, history and civilizations. All this information we have carried from your Earth to Ummo in our titanium crystals codified with data. We HAVE DEMONSTRATED to you our culture and our technology in purely descriptive form - so you cannot convert them or realize them practically. We have done this because we note with sadness that you employ your sciences primarily for war and the destruction of your own selves, which cont[inue] as your principal objective. You are like children playing with terrible and dangerous toys which will destroy you. WE CAN DO NOTHING! A cosmic law says that each world must take its own path, to survive or to perish. You have chosen the second. You are destroying your planet - annihilating your species, and contaminating your atmosphere and your seas until now this is irreversible. With sadness we contemplate your insanity, and understand that the remedy is only in yourselves. We can not look forward a great distance into your future because your psyche are completely unpredictable and capricious bordering on paranoia. As your elder brothers in this cosmos, we urgently desire with all our hearts your salvation. Do not destroy your beautiful blue planet, a rare atmospheric world that floats so majestically in space, so full of life. IT IS YOUR CHOICE. 
While it cannot be known exactly how influential the Ummites assistance has been since it was largely covert, it certainly appears to have been significant in sparking innovative scientific initiatives by range of technically competent professionals and private citizens. It can be concluded that the Ummite's main activity lies in sharing technical information, transforming scientific culture, and global education. The Ummites can assist in global solutions surrounding the transformation of scientific paradigms, development of environmentally friendly technologies, and educational reform.
