Well, the big bang theory is the best science have. It is not perfect, mind you.

Do you have a better theory?

You ended by saying you have a "belief"... That's cool and all that. However, it has nothing to do with science.

But if you want to have a scientific discussion, you can not go: "some parts of this theory might prove wrong, so I decide to go with pink elephants being the cause".

Get my point?

Oh, and there are scientific research to explain what you wrote, I however am not intelligent or well read enough to understand it.

But I urge you to do some research on the topic if it fascinates you! Please report your findings
