Even though they are technologically infinitely superior, able to travel at velocities surpassing the speed of light (able to "de-molecularize" themselves and use "worm holes" as conduits), we are asked to believe that when they finally get to Earth their first order of business is to probe the human rectum using proctology instruments dating back to horse and buggy days?
Actually, that's incorrect. Anal probes are NOT their first order of business. According to the voluminous "They've already visited us!" literature, these aliens' first order of business was to build the pyramids, erect Stonehenge, and place a giant rock in what is modern day Honduras--a rock so prodigious in its weight and dimensions that, even today, we don't have the cranes and levers capable of moving it.
Of course, saying dumb stuff like this raises more questions that it answers. So did these aliens bring this humongous rock with them? Was that part of the game plan--to transport a huge stone to Earth and drop it off in Central America, just to mess with our heads? Or did they travel light and produce this giant rock once they got here? Which raises another question: How does one "build" a rock?
As for constructing the pyramids, why would they do something like that? Why would they bother with it? And did they do it alone, stone by stone, or use local laborers? If they did it alone, that seems needlessly painstaking and time-consuming. You'd think they would rather have spent their time doing something more productive (anal probes?).
When I've posed that question to True Believers, they say the aliens probably used pyramids as navigational "landmarks." Again, an awkward question: So they can travel, literally, a trillion miles across the universe, but they can't find Mesopotamia without a landmark ("When you get to that big, pointy thing, Fred, you're going to wanna hang a sharp left").
Any amateur astronomer who's even casually considered extraterrestrial life has to agree with the conclusion reached by 19th century biologist and naturalist Thomas Huxley (1825-1895). What Huxley said makes utter sense.
According to Huxley, the universe is teeming with life. It is crawling with life forms of all sizes and shapes, most of them beyond our imagination. But because the universe is so large, and the distances between habitable planets so immense, no one is ever going to meet anyone. Never. Ever. We are alone and are forever going to remain alone.
Huxley used the example of two fruit flies--one living in Tahiti, the other living in Siberia. Let's say the odds of those two insects meeting each other were something in the neighborhood of 10,000,000 to one. Compared to the staggering odds of any life form on earth meeting any alien life form, those fruit flies hooking up is practically a sure thing. Add another twenty zeroes.
Consider: We haven't even discovered all the creatures that live in the oceans or all the creatures, from insects to mammals, that live in our vast rain forests. Granted, there's a lot of ocean to explore. But that's precisely the point. The universe is simply too mind-bogglingly big.
And here's the kicker: When Huxley made his observation, 150 years ago, the universe was thought to be a fraction of what today's scientists consider its actual size. Forget about alien life. If anyone's probing your anus, it's a likely a drunk fraternity member.
