Um nobody knows about alien life but i believe it. So maybe yes maybe no. Maybe you should buy a book on it. Have you seen the movie killer clowns from outer space. In the movie there are a bunch of aliens wrapping people in cotton candy too eat later
I believe life exists on other plants. It may not be in the same form as humans and animals but something exists. It's hard to believe with all the plants and galaxies out there that Earth is the only one with living organisms.
