Yes but every theory needs a beginning of things. The big bang is evolutions attempt, obviously some things are unexplainable, that does not mean however that you can just brush it off and say that's not evolution when ALL THEORIES NEED A BEGINNING. The big bang goes hand in hand with evolution as one whole theory does it not?
No it doesn't! you just do.... right now evidence points to Evolution..... It doesn't matter where the Universe came from, as far as Evolution itself is concerned. The great thing about science is we can say we don't know something. The Big bang or anything else you mentioned have nothing to do with the theory of Evolution. Again you are assuming all evolutioniest are Athiest
