Yeah but how do you know it was God? Were you there? I know you have had that said to you but actually it's quite a fair question. See for one there is to much corruption in the universe for me to believe that the bible made it all this way through history unchanged. I actually believe that the bible was written by the Romans to control the masses of people because religion seems to give people a common goal. The simple fact is that we will never know the answer. We weren't there and we can't travel through time. It was to long ago to accurately record historical evidence. That is original of course. Meaning untampered and nobody on earth that ever lived messed with it at all. Simply not possible
