Caveman, dinosaurs, and Adam and Eve?

We know there were cavemen and Dino's. If Adam and Eve were the first ones here were they too cave people or what? There is no mention of Dino's in the Bible and so where did they go or what? Were cavemen and Dino's just God's experiments to perfect the human race and he wiped them out for Adam and Eve's appearance? Or did Adam and Eve come first, descend into cavemen and then ascend into what we are now? Can you prove any of this or was the other guy right and we ascended from ameobas?
