What caused the big bang. Like, randomly there was nothing, and then there was something. Its creepy if you think about it.
EDIT: I know Physics has the answers guys! That's why I'm majoring in Physics! Of course I'm still doing Classical Physics, but yes, I know Physicist constantly drive to find the answer. A lot of it is higher math, which I have no skill in at the moment. I'm currently reading the "Elegant Universe", and I will keep any other suggested books in mind. But, even Neil deGrasse Tyson and Dawkins have acknowledged in interviews that no one knows exactly yet how the universe came into existence. But that's the beauty of science! We are trying to find out why with evidence!
But it still creeps me out thinking about the complexities of our existence. I will reword my statement to that.
