What is BP? Do they mean BC?
BP is "Before Present".
BP is Before Present. So 8000-9000 BP is roughly 6000-7000 BC. At least that is better on my eyes than the screwy BCE that some pc scholars have used.

Yes, since this is the year of Our Lord Jesus Christ 2005, he's trying to say circa 7,000 to 6,000 before Christ.
