Then there is the question of what an Extra Terrestrial Alien would be. IF there are intelligent ET Aliens, they might be almost unrecognizable as a species, and intercommunication might not even be a possibility. However, most discussions assume and ET Alien like this.
Anatomy Of An Alien
The popular vision of an ET Alien is rather the same everywhere, but with mass media, that is not surprising at all. In fact, it is to be expected, since media is largely involved in creating news, not reporting it.
Let’s look at ET. His head is large and bulbous, so that it can contain a larger brain. His fingers are long and slender, indicating that he no longer does manual labor because he has developed devices to do all of his work for him. He is small and fragile, because his technology has relieved him of the need for physical strength. His eyes are large, probably because he is into visual rather than physical activities. He wears no clothes, because he has progressed past the need for modesty. He carries no tools or weapons because his superior intellect allows him to control humans without physical interaction.
What can we discover about the ramifications of these physical properties? Look at our own evolution, and it is clear that each of these attributes is a natural evolutionary extrapolation of what we would look like if we continue to evolve along our current evolutionary path. Since it is natural for most people to assume that in order for ET Aliens to visit us they would have to be far advanced, this is then a natural expectation of what ET “should” look like.
If there had been no UFO flap, and no “sightings” of “abductions”, and people were asked to describe what an ET Alien would probably be like, they would all most likely come up with an “alien grey” or something very similar.
There is one other factor which is never talked about. If we assume that ET Aliens would naturally be far more advanced than we, it would be extremely unlikely that ANYONE would EVER propose that ET was “insectoid”, or “reptilian”, or a “bug-eyed monster”. It would be unthinkable, not to mention treasonable, to assume that any of those could be superior to us. The only entities which could possibly be superior to us is……….our own evolved selves.
Stereotypical ET Aliens are clearly the creation of the projection of our own advancing evolution. They are really the only likely form our imaginations would create, but they are certainly not what nature would be likely to create on a distant world. I would be greatly surprised if distant independent genesis and evolution produced beings that so closely resembled humans. There is no compelling reason that evolution should choose this form over the thousands of other possible forms in the complex chain of evolutionary development.
