discuss i myself think that it is possible there are actually aliens with a humanoid form, but the only explanation for that would be that those are humans that have evolved so much throughout time, that they take on the form of a small grey very thin person with a large head, and these humanoid aliens in fact are just evolved humans (a different species then) that are travelling back in time, via some sort of dimensional rift or something. but anyway i don't think that the idea of some god-like humanoid race donating life to earth and spreading around seeds throughout the galaxy is feasible, because of what knowledge has been attained on our own evolutionary history. i do think it's possible that non-humanoid aliens donated organic matter however. i also think it's possible life began from non-life. and in fact i don't think this has anything to do with spirituality or metaphysical, supernatural or other superphysical existence. obviously something like that has very little in common with what actually physically happens. what i am saying does conflict with *specific* "great faith" type belief systems for obvious reasons. i do however believe that it may be possible there is some "god-like" species that has evolved/adapted to a point where they no longer have use for physical bodies and are only physical energy. i don't see how this isn't possible considering that ecologies on other celestial bodies would be extremely different than this one.
