I had read somewhere I forgot where that someone wrote it may be more likely that aliens would be a branch of humanity or humanity is a branch from the alien civilizations. Chances would be branches from same civilization would be closer distance wise than totally unrelated ‘aliens’. Not that there wouldn’t be unrelated aliens somewhere that they would likely be really far away as compared with “cousin” aliens.
Which is prob why all the aliens in Star Trek are humanoid rather than weird looking creatures. ;)
Aliens could be demons for all I know.
