Archeology does have problem. They put the Clovis culture as the oldest culture for the America and now are saying that there were prior people to Clovis. As of now we don’t have fossils showing dinosaurs and humans at the same time period. Basically humans are up to 200,000-300,000 years ago.
The issue is that there were sea faring people populating the Americas. That is complex navigation while maintaining a population of young and elderly. They didn’t have a need of mammoths nor were not nomadic. So what archaeologists basically define human existence is being rewritten. The whole nomadic to farmer to civilization is not a clear cycle anymore.
The food chain for example can only support so many species. Apex predators take up space and as they go extinct leaves room for other apex predators. The dinosaurs basically occupied that kind of space and as they went extinct gave rise to mammals. The point is that even with the food chain analysis on can see the separation of dinosaur and humans.
