Impossible to answer factually since there are no documentable cases of alien contact (of the extraterrestrial variety). Assuming there is life somewhere on the multitude of planets in a Universe so vast as this one, and that some of that life has advanced beyond the microbial stage, it would exist in a multitude of forms as diverse as the environments in which it has evolved on each life-supporting planet, just as it does on this planet. So teeth, or something equivalent, seem probable somewhere. However, the existence of life elsewhere, while likely in some form, can still only be conjectured. There is no current observational evidence either way.
thats ridiculous. seriously?!?!? who questioned that?
As yet, we have not made contact with any aliens.
There is no evidence that aliens exist therefore the biology of aliens, if they do, is unknown
They are called Scardox Aliens.
If there are aliens
There are no aliens.
yes. we think other species are aliens because we dont know what they are. maybe aliens dont know about us and think we are aliens.
Aliens can be deported. You can not deport a citizen. Aliens cant vote Aliens can not run for political office
If we were there, we would be aliens. If they were here, they would be the aliens. Depends on the type of alien.
There are no such thing as aliens
Yes, there are aliens in California at a little market it has a U.F.O with aliens shopping for laser beams [the aliens and the U.F.O are models].
i think there are and they might be your own friends or some thing.
