Or you do if you look as if some of your ancestors were European. The Magdelanians were a widespread Paleolithic culture that left various artifacts, including art (pretty good art!), weapons, tools and a few what-is-its scattered across the continent, chasing the glaciers back North -- and who do not appear to have made Mankind's Worst Mistake* in their 8,000-year run.
What else they might have done, we don't know. They didn't work metal, so if it's not stone, bone or paint inside a cave, it didn't leave much trace.
* You might recognize this idea from L. Neil Smith's Pallas. It's not coincidence.
