People have been doing both ways for over 1 million years.
Terrible usage of terms, “modern human” used to reference homo sapien 74k years ago is not modern by any archaeological means. Modern Human needs to be defined as homo sapien sapien, the advent of abstract thought between 15k years to 25k years ago. the hand axe shown cleary does display abstract thought process. Before I would accept a modern human label i would expect at least a cored blade or bi-face showing pre-reasoned tooling rather than hitting 2 stones together to make one kind of sharp.
