Ah the matrix theory. You think therefore you are. You need to have faith that everything else exist. I mean do you questionin the chair you sit in? But who made everything something never comes from nothing Believe it or not The Big Bang was God doing. Read your bible and have a little faith God Bless you.
That's a question I have looked into and found some interesting info. Look up quantum physics. There's an experiment that had two different results when one was observed an one wasn't. Really mindblowing stuff!!
