I'm enjoying all the input and ideas on this very much. I personally have been interested in this type of pre-history ever since I was a kid. I always had a problem with the orgs. time frames and it was one of many things that convinced me that they were mistaken and I had to leave.
As to the Clovis culture I realize it is not the oldest evidence of man in North America, it is just so wide spread. Clovis artifacts are found from Florida to New Brunswick, west thru the entire continent. It is debated if they are from Europe or Asia, but that just makes it all the more interesting.
Many sites in N. and S. America are shedding light on the fact that man has been alive and well at least 15 thousand years or more in the "new world". There is so much evedence one could go on for hours. Thanks for the response.
