text: do you think humans could be aliens? it seems to be a viable theory. we don't really fit in on the earth, and our presence is destroying it.   one thing that you must admit -- that we might have been dropped off by aliens is just as, or more, believeable than the other fairy tales on creation. i would say that this is against both evolution and creationism.    if humans were not from earth then why would we have so many similar internal organs to other animals?  i mean i doubt any extraterrestrial creature could have a pig's heart transplanted into their body like humans can.  it could be that humans were in some way altered by aliens or our culture is influenced by aliens.  but this lacks any real evidence at present and is thus a very unlikly (but not impossible) case.  personally i think there are aliens of some sort but they are not amongst us in any conventional sense at the moment.
