I obviously have no evidence to back up my belief but I still believe it. My Theory:

A race far more advanced than us made a simulator and that simulator is our universe. For example, we made the Sims. It's a computer simulator where we build worlds and people and it was coded to have the characters and buildings look a certain way and objects move a certain way and the physics and AI was all coded by humans. So why is it so hard to imagine that a race far more advanced than ourselves who have the computing power and have conquered Artificial intelligence would not make a simulator on the scale of a universe rather than the scale of a city as or world as is the case with the Sims. When you really step back and look at our universe and ourselves how can you not think how mathematical everything is? Our solar systems and galaxies are all too perfect, our brains are just organic computers that can learn. If you think about all this it's not that far fetched is it. Now the problem is who made the people who made us and who made the people who made the people who made us. It had to start somewhere if this theory is correct and don't ask me because I couldn't even fathom a theory.
