Not enough time for any sort of an expanding Earth theory to account for large dinosaurs. They also find ancient stone structures which neither ancient nor modern technologies could account for (200-ton fitted stones etc.). Those also require reduced gravity, and were not created by dinosaurs and are not 70,000,000 years old.
One thing is for sure. There are more questions than answers on this stuff. I figure it doesn't hurt me to keep an open mind on a lot of this stuff. "Forbidden Archaeology" poses some really interesting questions about our planet and race's (human) history.
