God does as he pleases

If you read the account of creation in Genesis it does not go along with any of the main stream theory's about how the universe was created. Genesis says God created heaven and then separated the water on earth and in the sky.And then he separated the water from dry ground  and then planted seeds and then on the 3rd day he put the stars in place and the moon and maybe even the sun. doesn't seem to go with the big bang theory. What it comes down to is God speaks and it happens it doesn't have to make sense to us.
