Why would radiometric dating date the rock around dinosaurs at 65 million years, but the earth around mammoths at less than 50,000, if both died out with the flood? This isn't necessary for life to exist, but is consistent with observations and not a global flood.
Moreover, if dinosaurs existed within 10,000 years ago, they would still have C14, but to my knowledge, none do.
If hydrological sorting distributed the fossils, as is sometimes claimed, then why do dinosaur fossils only exist in a certain region of the geologic column, but some fossils, that are much the same shape such as a crocodile, exist outside that region and coincide with animals that bear no resemblence to them in any way.
The geologic column only makes sense if you consider:
The world is 4.5 billion years old.
The world appears 4.5 billions years old because of a vast theo-conspiracy to confuse people who seek knowledge from the world around them.
