James Brown:
if the water canopy existed that made the global flood, air pressure on the ground would be 10 000 pounds per square inch. To stop it turning to rain would require a temperature of at least 900 degrees.
If the flood happened - where are the fossils of animals exploding as pressure dropped catastrophically?
You are either a blinkered victim of the Watchtower Cult, or an ignorant fool.
Oh - and many creatures were much bigger than now because there was more oxygen in the atmosphere, so they COULD.
