So I dont want to know if there is extraterrestrial life out of there, because I already know. So I voted No

Universe is too big and big numbers are fun: impossible to state that Earth is an unicum (well probably is, but in another sense and we must conserve it as well as we can, instead of depredate it..).

I want just to add a little concept: lithopanspermia.
