Have you considered the possibility of dinosaurs living in a prior age? Perhaps the one Peter speaks of here: [2 Peter 3:5-7] for this is unobserved by them willingly, that the heavens were of old, and the earth out of water and through water standing together by the word of God, through which the then world, by water having been deluged, was destroyed; and the present heavens and the earth, by the same word are treasured, for fire being kept to a day of judgment and destruction of the impious men.
He's not speaking here of Noah's flood....it is a prior flood being referenced and this would indicate a prior creation. Compare "The heavens were of old" to "The present heavens". We have the same heavens today that Noah had...the Sun, Moon and the Stars. There weren't any changes to the heavens after Noah's flood.
interesting, thanks
FYI, there is a tradition in the Midrash that there were many floods:
“The deluge in the time of Noah was by no means the only flood with which this earth was visited. The first flood did its work of destruction as far as Jaffé, and the one of Noah’s days extended to Barbary.”
