I never tried to make the timeline 6-8 thousand years .I believe it is older. I didn't make an attempt to make people and dinosaurs exit at the same time. I stated that the bibles position is that they did.
One land mass before the flood. Pangea. During the flood, the fountains of the deep shot water up. Imagine the catastrophic nightmare. It gave us the continents today.
God's knowledge of knowing Dinos wouldn't make it after the flood because of the environmental change, why waste Noah's time hauling two T-Rex's around.
The flood explains their extinction and your fossils, locations, layers, etc. Your statement that the weaponry didn't exit for man to survive at the same time as they did is weak and kinda laughable. Too much Jurassic Park, VanMan.
