It probably depends on the race of space aliens involved. As of yet, scientists have not found any evidence that space aliens exist.
They would behave according to the environment and lifestyle given. Also by the intelligence of the creature.
they will kill us all!!!!! Aliens from outer space, despite all UFO cultists and anecdotal evidence from people claiming to have been abducted, and so forth, remain entirely hypothetical. We have no clear evidence that such aliens exist or that they have ever visited the Earth. There may, of course, be aliens living on other planets, but we have absolutely no way of knowing whether they will ever visit the Earth, and no way of knowing how they would behave if they were to do so. Many people, including myself, would like to believe that if such aliens were to visit the Earth they would do so in the spirit of scientific investigation of the universe, and they furthermore would freely share their knowledge with human scientists here on Earth. But we cannot really know what they may wish to do. I think it is unlikely that they would come to Earth in order to eat us, but I cannot rule it out. Realistically, the stars are extremely far away, and it would be extremely difficult to travel from one star to another. Very likely, it is not going to happen. Aliens are unlikely to visit the Earth, and therefore the question won't arise, of how they would behave were they to do so.
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
