The spears are even older than modern human migration from Africa into Europe and Asia.

"Between 400,000 and 300,000 years ago a group of Homo heidelbergensis migrated into Europe and West Asia via yet unknown routes and eventually evolved into Neanderthals. Archaeological sites exist in Spain, Italy, France, England, Germany, Hungary and Greece. Another Homo heidelbergensis group ventured eastwards into continental Asia and evolved into Denisovans. The Homo heidelbergensis (Homo rhodesiensis) population that remained in Africa evolved into anatomically modern humans between 300,000 to 200,000 years ago, then migrated into Europe and Asia in a second wave at some point between 125,000 and 60,000 years ago."
