Another HUGE nail in the coffin for creationism: [Spirituality & Religion]

[b]If Noah's flood really happened, why do we never find a dinosaur in the same geological layer as a human or a dog?[/b]
Why no whales in the same layer as mosasaurs?
Why no Apatosaurs in the same layer as elephants?

If all the animals were overcome by the flood at around the same time, why do we NEVER see these animals in the same fossil layers [i]anywhere [/i]on earth?
