If we were to take the Old Testament literally, that is a 6000 year old earth and the like.
When would the flood have happened?
I found this (http://www.nwcreation.net/biblechrono.html) that said:
Total - from creation to flood 1656 Years
2344 BC.
I would like to hear other people on this matter though.

Of course this would mean that the human race never really learned about the cultivation of race, beer wasn't a human invention.
The early history of Egypt was probably an illusion.
The Bristlecone pine tree known as Methuselah was probably either really sturdy, or not as old as we think it was (I wish I could talk to trees now). The Văn Lang kingdom of what is now Veitnam probably had to reform itself after the flood.
Of course this is the tip of the iceberg.
