In answer to your question, Garath, I will post another excerpt from my book, UFOs and Nukes, which is available only at ufohastings.com.

Why Do Aliens Reportedly Look Similar To Humans?
<O> </O>Skeptics also ask, “Why are aliens always described as humanoid in appearance by those who claim to have seen them? Isn’t this highly unlikely, given that evolution on different planets would have proceeded differently?” <O></O>
<O> </O>
To state the obvious, the use of the term “humanoid” is our own projection onto another life form that looks something like us. Setting aside, for the moment, the descriptions of alien beings provided by the UFO abductees, and using only the eyewitness reports of beings walking or standing near landed UFOs, or observed through a UFO’s windows, there are at least three (and probably many more) potential reasons why aliens reportedly look somewhat human.<O></O>
<O> </O>
First, consider the possibility that the “humanoid” form is a universally-distributed, highly-successful, evolutionary model for sentient beings. Importantly, such life forms would, as we do, have two forward-facing eyes, which permit stereoscopic vision, so that depth-perception is possible. They/we also have an erect, bipedal stance which permits them/us to gradually develop hands that can grip tools and, eventually, build things—including spaceships. <O></O>
<O> </O>
In fact, one might argue that other types of intelligences, perhaps many superior to ourselves, who did not develop hands as part of their evolutionary progression, would not be capable of building craft to travel in space and, therefore, could not arrive here and present themselves to humans. In other words, while other non-humanoid forms of intelligent life probably exist in the Universe, they might be restricted to their own worlds. At the moment, this can not be proved, one way or the other, but such a theory would explain why those advanced races who make it to Earth in spaceships are apparently only comprised ofbeings who have stereoscopic eyes, stand on two feet, and have hands with that can grasp things, including tools.<O></O>
<O> </O>
Of course, different physical environments on Earth appear to modify a creature’s specific attributes, for example, the size of its eyes, in response to the ambient light level, or the degree of coverage and density of hair or fur, depending on the local temperature-range, and so on. Consequently, it is not unreasonable to suggest that the hypothesized universal pattern for an erect, bipedal, intelligent being—if such a generic pattern does indeed exist—would evolve somewhat or even very differently on different planets, resulting in a wide range of variations in the being’s height, weight, skin color, facial features, the length and number of fingers, as well as many other features. <O></O>
<O> </O>
Consequently, one would expect to find variation, rather than uniformity, in the appearance of aliens—if they have different origins—which is precisely what has been reported by UFO sighting witnesses around the world. Moreover, in my view, the degree of diversity described is so pronounced, from case to case, so as to rule out the possibility that all of these beings hail from the same planet, just as Caucasian, Negroid, and Mongolian races all hail from our own planet. <O></O>
<O> </O>
Perhaps most notably, given what our own paleontologists have learned about human evolution, with brain and cranium sizes generally increasing over time, one might reasonably speculate that the many witness reports of aliens having a very large head, relative to their much shorter, slender body, would be a predictable evolutionary development for an extremely advanced humanoid. (However, it must be said, other aliens emerging from UFOs reportedly have head-to-body ratios similar to humans.)<O></O>
<O> </O>
A second possible explanation for why humans look somewhat like aliens is because we are them. If aliens have been coming here for a very long time, it is not out of the question that human evolution has been deliberately modified by outside influences—really outside influences. This possibility has been traditionally rejected by biologists, if for no other reason than the long-held belief that inter-species interbreeding, between humans and aliens, would be highly implausible, if not impossible. <O></O>
<O> </O>
However, this argument becomes increasingly less viable with every passing year, in our brave new world of cloning, implanting genes from one species into another, and the other already practiced or proposed marvels of human genetic engineering. If we have been able to accomplish these feats, after only a few decades of research, imagine what an advanced, space faring race might achieve while visiting a primitive planet such as Earth, populated by proto-humans. <O></O>
<O> </O>
Needless to say, the proposal that another race created, or even dramatically altered our own understandably rankles traditionally-religious persons, of all faiths, who sincerely and unquestionably believe that the Bible, or the Koran, or whatever, states that God alone created humankind in His own image. Nevertheless, while alien intervention in our own evolution may have never occurred, can it really be ruled out as a possibility by those who do not adhere to traditional beliefs? At this point, we have entered the arena of religious argument, a place in which I will tread no further.<O></O>
<O></O>
A third possible reason that aliens reportedly looked somewhat like humans involves the now-respectable concept of time-travel. One might be surprised by the number of theoretical physicists who currently propose its reality, in one form or another, either with or without the classic time-travel paradoxes noted by scientists and science fiction writers alike. In any event, if time travel is indeed possible, then perhaps some of the sightings of “humanoids” with huge heads and big bug eyes are actually sightings of humans from the very distant future, who have evolved into something similar to, but not quite like, today’s homo sapiens. <O></O>
<O> </O>
However, in addition to these sightings, there are also the occasional reports of UFO occupants who are virtually human in appearance, down to the smallest detail. If these particular beings are humans from the future—and not some other, technologically more advanced species with an evolutionary path nearly identical to ours—then the clear implication is that our species will utilize time travel in the relatively near future, perhaps a few thousand years from now, before evolution significantly modifies our physical appearance. <O></O>
<O> </O>
Regardless, one can argue that time travel—if it exists—might explain some of the reports of UFOnauts who have a human-like appearance. Having said that, however, I will assert that given the great diversity of the UFO occupants’ physical forms, as reported by sighting witnesses, the future-humans hypothesis alone can not account for all of the reports. Therefore, in addition to the possibility that some of the beings observed near landed UFOs are indeed humans from our future, many others are very probably true “aliens” from various advanced civilizations scattered throughout the galaxy or, perhaps, the whole universe/multiverse/parallel dimension matrix. (Man, astronomy and cosmology were certainly simpler to explain when I was a kid!) <O></O>
