NOTE: This post is written from the (unproven) perspective that there are extraterrestrial, or otherwise foreign to this world, visitors to this planet and that they look like the popular conception of an alien. If you do not believe this or do not care for an exercise in conjecture, this might not be a good post for you.
If you ask someone to draw an alien, whether that someone be a young child or middle aged adult, you'll probably get something back like this.
A large head that is bulbous and bald. Almond-shaped eyes that are solid black and at an angle. Diminutive stature. Gray skin. This has become the standard, accepted image of what an alien looks like. There are many reasons for this. One would be pop culture images, such as the aliens shown at the end of Close Encounters of the Third Kind or the cover of Whitley Streiber's Communion. Both of these images became infused in our collective consciousness...but both were based on descriptions given by people who had claimed to have actually seen aliens and in the case of Communion, it was Streiber's very own purported experiences with abduction. In fact, descriptions of the alien type now known as "the Gray" go back at least as far as the famous abduction case of Barney and Betty Hill in the 1950s.
Skeptics have poked at these uniform descriptions of aliens, citing how improbable it is that intelligent life would have any kind of humanoid appearance. So why then do the Grays look like they do? Here are a few theories:
1.) It's just how life goes. Bipedal humanoids with large craniums might just be the most logical form for intelligent life to take. It allows for speed, dexterity, the construction of tools, and many other advantages that could place a lifeform at the top of its ecological food chain, thereby giving it enough time to evolve and commit to massive undertakings, such as the construction of spacecraft.
2.) We are them. An Ancient Astronaut theorist will argue that aliens added in their own genetic material to the DNA of our most distant ape-like ancestors. Humanity is one big alien colony and that is why we have the same basic shape as they do. But why would the aliens do that? To gain slave labor? An army? A "farm" of genetic material? Those are questions without solid resolutions, but a great many abductees report medical tests, the harvesting of tissue samples (the nefarious "butt probe"), and even crossbreeding experiments. That could point to our "use" for the Grays.
3) They are us. Anthropologists once speculated what humans might look like after another million years of evolution. Here are a few of their musings:
-We would have less need for hair as we wear a great deal more clothes than our ancestors did.
-We would shrink in size as we tend to do less physical labor on the whole.
-We would have larger heads as we (hopefully) grow more intelligent and have more information to process.
-We would have larger eyes as we would be taking this information in from multiple viewscreens.
I don't know about you but that sounds like a Gray. Are the Gray aliens actually humans time traveling from the far future? As stated previously, abductess report a harvesting of genetic material. Has human DNA weakened somehow in the future and they need ours?
The one area that this does not jive with anthropological speculation is skin color. It is thought that as societal taboos breakdown, there will continue to be more interracial relationships. It is no longer unheard of for say, a white man to fall in love with a Hispanic woman. Offspring from these kinds of relations will go on to reproduce with others of mixed race. This could eventually lead to all of humanity being one color, a sort of "coffee with cream" look, not gray.
4) Panspermia. Somewhere in the vast reaches of space, an alien civilization sent out probes that seeded many lifeless worlds with the DNA of their own species. This civilization happened to be humanoid, therefore there are several planets of intelligent, bipedal aliens. Why would aliens do this? Perhaps they were dying and wished a way to live on. Maybe they were laying the groundwork for eventual terraforming later on. Sound crazy? This hypothesis was originated in part by Dr. Francis Crick, one of the co-discoverers of DNA. And yes, there was an episode of Star Trek: The Next Generation about this. Pretty good one, too.
5) Drones. Like I said in a previous post, the Grays might be biomechanical probes or drones sent by aliens. Maybe they were constructed to look the way they do because we already have that image lodged in our psychological subconscious? That way they could more easily interact with us? Meaning, conduct lab tests on us? If abduction accounts are to be believed, someone has definitely taken an interest in the genetic make-up of our species.
6) Cryptoterrestrials. The Gray aliens are not aliens at all. They are an offshoot of humans and they live hidden somewhere on our world. This is a hypothesis developed by late, great Fortean researcher, Mac Tonnies. He published a posthumous book on the subject and I will write more on this theory once I've actually done the reading.
