Look I'll covience you the flood did not happen. Supposedly this flood happened, during a time when civilization was in existance, so this flood could not go back beyond thirty thosand years. Therefore, to keep a mass extinction from happening to the insects, Noah would have to fit trillions of species of insects on his boat to keep them from dying. Also, he would have to fit trillions of species of plants and yes animals, we are talking from polar bears, to every specie of bird.
It is totally absurd, it did not happen.
So now I ask you, what is wrong with saying, God did not write the bible, men wrote the bible. Perhaps all religion is, it is a study of who or what God is, and maybe when enough time goes by the human race will figure it out? With poetry, philosophy, Theology, and science, we just might figure it out.
To me, I believe that which made all of life on Earth was the natural process of Evolution. So if you define God to be all that made life on the Earth, then yes I believe in God, because that is evolution.
Keep searching, the answers are out there.
