This is done because it is by far the methods most- if not all, sane humans prefer.
Telepathically, according to SOME alleged abductees.
Some UFO abductees say that they saw alien life that appeared humanoid. So ya!
Some would say aliens and doctors both examine people. Some who believe in outer space aliens believe they examine humans to try and understand humans.
Examine humans
We can only speculate until we have some to examine.
If they are advanced enough to visit our planet it stands to reason that they would have weapons that could do humans a great amount of harm. For alien abductees, they are in pain and feel horrified and sometimes even tortured at the hands of the abductors.
No, not personally. I believe that aliens are afraid of me.
Aliens are from outer space. Aliens are amazing creatures that no one knows about. Everyone thinks the stars are balls of gas, pssh! We all know they're aliens holding light bulbs. :) hope that helped. i love the last one. (:
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.
