"Homo sapiens Sapiens (modern man) has only been on the planet for about 40,000 years."

The most widely accepted date is 125,000 years.

True, as to Homo Sapien Neadertalensis aka Neanderthal "Man", and other almost human variants of Homo such as Homo Habilis ,
But true humans, (you and me) are Homo Sapien Sapien and did not appear until about 40,000 years ago.
