If you reject that statement, you will also deny every other cardinal truth in the Scriptures. Joe said he believed the record of creation just as it was written. Charlie was an unbeliever, and went to great lengths in giving his own theory of how the world began and then how life developed from a primordial cell through reptiles, monkeys, and up to man. It was a good question. In a court of law, eyewitness testimony carries the most weight.
Hearsay testimony is thrown out.
The same is true of creation. God was there, and His Word can be trusted. You will be able to trust the Bible when you have come to trust its Author.
