Oldest man made object is a chert and atalatl point. It essentially is an arrowhead. Atalatls were used before mankind developed arrows.
Archeologist guessed it is 10-15,000 years old. Found on my property just 50 feet from my back door at my house in Flagstaff.
I have a lot of 1,000 plus year old pottery shreds on my property too. A metric _____ of it.
WOW, that is Ultra Cool!
