No one knows. It might vary depending on the exact races and cultures of aliens.
idk know well becaus well no one knows if alians really exist but they might be real and the might be friendly we just have to wait and see if they are. hope that helps.(>^_^)>
There's no conclusive proof that aliens (in the sense of non-human extraterrestrial intelligences) actually exist. If they do, it's at least possible that they could be friendly.
There is no proof that aliens exist. I believe there is no such thing as aliens. Has anyone seen an alien ship? Has anyone seen an alien? No.
Nothing. There are no aliens known to exist.
If space aliens do indeed exist, they exist for the same reasons we exist. Whatver those reasons may be.
There is no evidence that aliens exist therefore the biology of aliens, if they do, is unknown
No
aliens, Might exist but their are rumours that they probe people.
its not that u are cray if u think aliens exist ,if someone says the exist and someone says they dont exist , just respect there answers
If we were there, we would be aliens. If they were here, they would be the aliens. Depends on the type of alien.
I don't think they eat anything. You have to exist to need food, and no aliens are as yet known to exist.
if aliens do exist, then yes
