Can you hear me, Dave...?

Quite contrary to what a probable 99% of the other people in this Geocities neighborhood believe, I don’t think that there is sufficient evidence to believe that we have been visited by them. I don’t think that it’s impossible, but only that is unlikely. Of one thing, however, I am quite convinced. If they are here, they do not have two arms, two legs, walk upright, a big bald head, pale skin, big lidless eyes, or any other feature even remotely resembling humans or the popular descriptions of The National Inquirer or Hard Copy. Here is why:

Even after a couple of billion years of Evolution (or six thousand of creation - you pick your favorite...) humans have traveled no farther than their own solar system. Further, according to our current understanding of the laws of physics, it would be some time before we could even begin to come close to the technology required to detect and then explore other planets as some say they are exploring ours. It would not be irresponsible to state then, I would think, that any beings performing such exploration here would be far in advance of us in many if not all areas of science including engineering and biology.

Further, any creatures which could survive long enough to form such a civilization would surely have an instinct evolved (or created) within them which would make them act in such a way that would allow the beings, individually or collectively, to endure (i.e. exist) for as long as possible, and such an instinct would almost necessarily be stronger than just about any other, just as in the species which survive on the Earth today.

In fact, even though we live on the same planet, at the same time, with even the same basic DNA structure, very few of the other earthly organisms (perhaps none) resemble us as closely as the supposed creatures popping in to say “Hi!” from across the Galaxy. Even more compelling, given the highly probable advanced technology, coupled with the almost undeniable urge to survive, any Alien visitor that is purely biological is almost inconceivable to the point of laughable. Even our lowly brains can come up with artificial limbs and improved organs. Contact lenses, artificial hearts, and even breast implants all strongly point to a trend who’s inevitable end would seem to be, if not total artificiality, then at least a strong combination of organic and inorganic which would not nearly resemble what we call life today. As Arthur C. Clark pointed out in 2001: A Space Odessy, they would not be visiting us in spaceships...they would BE spaceships.
