Did dinousers live befoore humens

The last dinosaurs (except birds which are close relatives) died about 65 million years ago. The first human like creatures lived about 3 million years ago, with modern humans not appearing until less than 100,000 years ago. No human ever saw a living dinosaur. The largest mammals alive when dinosaurs lived were only a bit bigger than a very large modern rat, and were about as smart.

And for what its worth, the earliest dinosaurs lived roughly 200 million years ago. That's more than 200,000 times longer than the earliest modern humans.

Yes, dinosaurs lived before humans, in every sense of the Words.
