Inspired by so many things.
Primarily, life forms that are NOT human.
I've always wanted to go into space....I don't necessarily want to be an astronaut for a living or anything, but I'd love to go up and see the stars at least once. The vastness of the universe has always fascinated me. The fact that something can go on and on forever and ever blows my mind out to Pluto.
I don't see how out of all the unexplored and undiscovered planets, we can be the only ones.
