it also seems likely that ancient men spent a great deal of time and energy oberving and contemplating the stars while never really understanding them. I would bet that changes in the heavens 20,000 years ago did not go unnoticed. A supernova, for example, would have been big news even then; although it would be misunderstood and, consequently, would be described in a manner that was not altogether understandable by modern men.
cannot be, all was nothing 6001 years ago
