Did cave people ever exist when dinosaurs did?

Cavemen didn't actually exist technically.... We know that the dinosaurs died out approximately 65 million years ago. On the other hand, the earliest hominins (our ancestors) only appeared about 7 million years ago. When people speak of 'cave men', they usually mean the Neanderthals - although all early humans lived in caves if they were available. The Neanderthals lived in Europe from about 200,000 years ago. So, cavemen certainly did not exist when dinosaurs did.
