I'm always a sucker for anything to do with aliens or space in general.
It's fun thinking of theories and what could possibly be out there. I myself love believing that there are intelligent beings out there somewhere, it's just so vast. They could have possibly visited our planet or perhaps even been monitoring our way of life. I mean assuming they are actually real, I'm sure they'd have far more advanced technology that is way ahead of ours. They could easily swing by undetected.
Anyways I enjoy theories such as yours. ^^
