I think there's probably life out there somewhere,and it's probably wondering if there's life out there.
Perfect, there should be other life out there and they're either wondering weather there is other life, living like cavemen with no thoughts at all or they have uber-cool technology and know that there is other life forms.
I personally think that aliens are real, but then I don't think they're real at times. I do, however, think that cropcircles are lies and are fake.
I have seen UFOs before (Not the alien UFOs, but just UFOs) and I've wondered if it was some military plane or just an airplane flying by. But I have seen odd looking lights in the sky before, out in the country.
