* Why did lifespans drop so dramatically after the flood? Shem ended up living another 600 years post-flood, outliving TEN generations of his progeny (lol btw). Its not due to the genetic bottle neck because the two babies born before the flood ended up living short lives like everyone else.
* How were all the animals fed? An elephant consumes 700-1000 pounds of food and water each day, for example.
* How did all the animals fit. If it was only a few basic animal "kinds" than how did hyperevolution give us so much variety in just a few thousand years.
* (from above) Where was the room in the ark for potential converts of Noah's ministry?
* How did all these single pairs of animls manage to avoid injury and plague and predation and other problems to repopulate their entire species?
* What did predators eat after the flood? All the animals were locked up and essential to repopulation.
* What did herbervores eat? Many of these animals require extremely precise diets. How are, for example, pandas finding hundreds of pounds of fresh bamboo each day? The entire eco system is crushed, drowned and destroyed.
* Why is there evidence of cataclysmic world events from times past, HUNDREDS OF MILLIONS OF YEARS AGO, that are crystal clear in geology and fossil evidence but there is literelly ZERO evidence of this event just 4 thousand years ago?
* How did the fish survive? (duh, in the water) -- No! Fish don't just survive in any sort of water. Fresh water fish survive in fresh water. Brackish water fish in brackish water. Fresh water fish in fresh water. Coral reef fish in shallow water. You can't just add miles of water on top of that, mix a toxic stew of waters together and say 'yeah the fish will surive.' You can't suddenly thrust a coral reef thousands of feet below the surface and expect anything (or the reefs themselves) to not be crushed in the process.
* Why do 40,000 years of ice cores and 100,000 years of coral reef build up show no evidence of this (much less survive the immense pressure of being under so much water)?
* Why are you stupid enough to believe a water canopy could exist?
