You can present all the data you like, but it will fall on deaf ears. Creationists put all the geology, strata, fossils, Grand Canyons, down to the flood. It turned over everything, destroyed most life (fossils) and pushed up the mountains.
If you argue that this is physically impossible in the 6000 year timeframe, or impossible for a single flood event, they will simply come back with the “God can do anything” bit.
Probably the best evidence geologist have is taking the geological extreme – Everest. The summit of Everest is made of limestone that was formed from the shells of trillions of ocean creatures. For a flood event to push up the ocean bed to nearly 9 km above sea level, it would have to have been a gargantuan cataclysmic event. Tsunamis many kilometers high would have raged all over the world, and from all the other mountain ranges being pushed up at the same time. This would hardly be good sailing conditions for Noahs wooden boat, would it?
But even then, the creationists would argue that God protected Noah’s ark from the mayhem, which would make anyone wonder why he bothered to get Noah to build an ark in the first place. But they would say “to test his faith”.
Can’t win, I’m afraid. We just need to ignore them.
