Coming from a purely scientific viewpoint, it's given that there are other intelligent civilizations out there. I refer you all to a terrifying-looking mathematical bit called the Drake Equation. N=R•Fp•Ne•Fl•Fi•Fc•L. Nasty-looking, innit? It's actually really simple if you break it down. The full explanation is this: The number of civilizations we can detect = The rate of star formation • stars that form planets • number of planets capable of supporting life • planets that develop life • planets that develop intelligent life • life that can communicate on an interplanetary scale • period of time the civilization exists for. Example: so far Earth is the only planet known to support life. Humans have been knocking around this dirtball for millions of years, but we couldn't really communicate with (theoretically, at least) an extrasolar civilization until the 1950s. And since then we've come damn close to eradicating ourselves more times than I care to think of. Say the Cuban Missile Crisis turned into a full nuclear war. That's 20 years from the development of nuclear weapons to our extinction, and about 10 years of blasting signals out into space. There's no way we're the only civilization to do something like that.
Now, the harder part about alien life is whether or not we've talked to them, so to speak. The number of phenomena associated with alien life is positively stupid. UFOs, Roswell, "telepathic communication", alien abduction...the list is ridiculously long. I tend to cut that down quite a bit. I figure most UFO sightings are either atmospheric anomalies or military test craft (that's not to say there haven't been aliens over Earth, but they're not as common as you might think). Telepathic communication is a load of bunk as far as I'm concerned. I've got a few ideas on Roswell I'll mention later. As for abductions, I think a race advanced enough to travel between solar systems probably have better things to do than go around probing us primates. Now, that's not to say I don't think that someone somewhere knows the truth about alien life, but there are too many idiotic conspiracies out there to get into on that.
The exact biology of extraterrestrials is also rather contested. The most common reports are, of course, the Greys, as made popular in dozens of sci-fi movies and TV shows. About four feet tall, big eyes, no nose, tiny mouth, and grey to greenish skin. Associated with the abduction phenomenon quite often. Another popular one (thanks to that maniac David Icke) is the Reptilian. Standing anywhere between 6 and 10 feet tall, covered in scales and looking distinctly lizardy, the Reptoids as they're also known are said to be carnivorous and may eat human flesh. Bit of a stretch of the imagination far as I'm concerned. Next up are the Nordics, known by about a dozen alternate names. Tall humans with blond hair and blue eyes. Of course, there are probably more types of alien than we can imagine, but those three are the most common.
|A Grey. Not that I need a picture for these guys.|
Reticuli, a binary solar system approximately 39 light-years from earth. There's no actual evidence that there are any planets in the ζ Reticuli system, but that doesn't stop anyone. Many reports put them as either one of two archetypes: sadistic researchers with a deep interest in probing human bodily cavities, or "saviours from the stars", here to save mankind from ourselves. A lot of reports put them as being able to communicate telepathically. I've got a theory on this. The large eyes and heads that define this race point to one of two things: a semi-aquatic nature, or evolution in a dark environment. Large eyes with immense pupils (assuming they even have pupils), and a bulbous head housing a sonar organ would both help immensely in navigating a dark world, one of mostly water, or an underground habitat. Sonar/echolocation abilities could also explain the tendency to communication without a familiar (to us, at least) vocal method.
|A Reptilian. Or a bad acid trip, you decide.|
|An entity whose name I'm not typing out.|
So that's that. A general overview of my theories on the top three alien races. And no Star Wars references, how much better can it get? And as someone (I think it was probably Leonard Nimoy) once said, keep watching the skies!
