False Alien

A digital work based of a doodle. I think a Vitara might of ripped off the missing chunk of this guy's helmet.

If I've said it before, I'll say it again; I find the Grey Aliens of popular culture to be too humanoid for me to find probable. While it is not impossible that something out there could evolve to resemble us, the infinite diversity and potential of life makes that both unlikely and unimaginative. If the Greys do exist (which I sincerely doubt), I think they are either future or alternate humans, something more closely related to us. Although, I think their outward appearances would probably just be the result of genetic engineering rather than the wearing of a suit (as I've shown here).
