Man I believe in aliens and UFO's.
It's so hard not to believe when "there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarfs in the Milky Way, 11 billion of which may be orbiting Sun-like stars."
I'm open to a lot of space theories, people possibly living on Mars in the past, or living underground.
