Creation is 11,023 bc and the flood was 4990 bc. What about those do you want to discuss. I have already said it is possible for some kind of creation to have happened at that time. I do not go as far as to say the universe was made then, because evidence seems to suggest otherwise.
That is as far as I can go with it, and have no reason to really think some kind of creation couldn't have taken place at that time.
The flood in 4990 bc, as to the extent of the flood, I am not sure, I am not sure of a lot back then. We have much science, but no science can discount a major flood, even if it did not cover the entire earth. There is evidence of many large floods. So again, I don't go as far as him and say with certainty, that the earth was completely covered.
I don't see how that changes the time line though.
So if you are familiar with it enough, feel free to comment.
