God does not exist in my opinion.
Something that could be the explanation of the life, universe, time traveling, gravity, destiny and whatnot: I think matter always circulates through space. The big bang occurred several times, but at the same time. It happened when it happened, I can't explain this. So the big bang happened, all matter spreads out all over space. The building bricks have always existed. So billions and billions of years passed, the universe stopped spreading, and matter is turning into dark matter, making it heavier. (fourth dimension, stuff I can't explain, I should be able to demonstrate how a 4D cube would look like, thanks to toribash modding) At a certain moment, all the matter recollect themselves, making a big, shrinking ball, traveling through time faster and faster. On a past moment, the ball explodes. The big bang. You will live your life again, and again, and again, and again, and etc. How it started is something I don't know.
Help me reconstruct my theory, because I suck at explaining things, okay? Thank you.
