aliens don't exist and never will

we are the only ones in the universe

even if aliens existed,they would have a different dimension

they should have developed around the same time as earth did from the beginning of the universe and have the same kind of materials as us to even realize that they are there

god created humans and we were perfect (except for the colored ones, and any female, and liberals of course .. but the point is i'm perfect) so god never created again.  ...or at least that's what my daddy told me right before beating me for asking such a flippant question.
