You accept that a big bang happened for no reason, and then your ancestor evolved from a rock in to a fish and then you randomly ended up on a Christian discussion forum...?
The rest of your post is simply naive.
I wasn't there when God created the universe, but it had to be one huge bang when he spoke it into existence. It wasn't a rock that God used to create man, it was clay. Many features of man have changed (evolved) since God kicked him out of Eden. Here are the important facts about the the universe.
God was before it was.
God was at the beginning of time as we know it
God was from the beginning until today
God is today
And finally, God will be here forever more
And the most important thing is that He has provided a way for you, me, and everyone else to be with Him forever more
Jesus said that He is the way, the truth, and the light. We are to look to Him, not the details (they are not included in the creation scriptures) of how the universe was created. Why? Because he finished that statement with "No one gets to the Father except by me."
