Does anybody else think about this? It hurts my head.

I OFTEN FIND MYSELF WONDERING.. WHO WAS THE FIRST EVER BEING TO EXIST, PAST GOD AND EVERYTHING, HOW DID IT ALL START? HOW DID EVERYTHING HAPPEN, NOT JUST OUR UNIVERSE, EVERYTHING, THE VERY MEANING OF EXISTENCE, HOW ARE WE HERE? WAS IT ALL JUST WHITE AND SUDDENLY A POWERFUL BEING APPEARED OUT OF NOWHERE?? IF SO.. HOW? HOW WAS NOWHERE THERE? *INTENSE THINKING*
