The so called validation of the Christian Gospels is because of the eyewitness accounts of those related to the events that are written to have occured ,by either first hand or second hand witnesses.
We have no such validation of the Creation account only by someone so far removed from the event being more than 2000 years after the event
How reliable would that testimony be in a court of law ?
And their is no previous account that Moses refers to where he basis his knowledge on , in other words we are supposed to believe that jehovah God did not give any human information or knowledge about his creation until 2000 years after he had done so.? Not even to "Noah who found favour in the eyes of the Lord" ?
