Of course I believe in aliens. The universe is HUGE. I can't imagine the Earth being the only planet with life on it. I mean come on people, we're really not that special. Sure we can think, but in the grand scheme of things we're really quite insignificant. This planet could die and nothing in the universe would really care.
I found a village with a desert temple in it. Didn't know what it was and walked in. Fell down the hole. I wasn't sure what the pressure plate did. Stepped on it.
