It can be true, but there is no proof. I found it interesting when such an idea was brought up in "Ancient Aliens" on the History channel.
Maybe similar with 'outlander' movie
There are so many things that could not be a falsifiable hypothesis. One statement that is not falsifiable is that humans need air to breathe.
No, aliens do not need a passport to travel to Earth as there is no confirmed evidence of extraterrestrial life visiting our planet.
Aliens probably could live on earth. As far as we know there is no life that can survive with out water food and oxygen.
There is no proof that life exists anywhere but Earth.
There are no aliens known to exist, in real life. Sorry. Someone has to be the first form of intelligent life in the universe, and it might well be us.
Aliens brought life to Earth. The end.
There is no factual evidence or record of aliens arriving on Earth. The existence of extraterrestrial life visiting our planet remains a mystery and a topic of speculation rather than a confirmed event.
No, it is not true that Martians are aliens. The term "Martian" refers to beings or things that come from or are associated with the planet Mars. While the possibility of life existing on Mars is still being explored, there is no confirmed evidence of aliens or extraterrestrial life on Mars or any other planet.
ALIENS EXIST ON EARTH................................ There are no Aliens Get a Grip with Your life MORON! SOD!
it could affect us if aliens come to earth but i cant say anything couse aliens havent been discovered
Aliens, as people know, are living beings outside of the Earth. Scientists have not even discovered bacteria outside of the Earth ( as far as I know). So I don't think aliens can breath underwater, maybe in science fiction movies, but not in real life.
