How could science disprove God's existence?

Quantum Physic have proved that the smallest building blocks of the universe are essentially random and seem to have a will of their own. Also, isnt the big bang theory one of the most profound proofs of God's existence. A random occurrence of random particles forming together to create the universe. Sounds like something in creation. I agree though it could be just random, but so are all the smallest particles so if there is no science to them, then it has to something or someone behind them. Also what is wrong with evolution. Did God say thou must interpret Genesis literally. To me it seems more than quite symbolic. A tree, fruit, snake, nakedness (innocence), a garden. Could Genesis not be the symbolic tale that was ped down through primitive cultures to tell the tale of evolution of our ancestors into a human being? Like on each day seems quite consistent with the process evolution must take. Whose to say how God measures or did measure days? When does science ever disprove God. Does it not more prove God even more?
