The simple truth is this. People only try to disprove that Dinosaurs exist because it threatens religious leaders power across the globe. If dinosaurs exist, and no holy books bother to explain them, then it's a glaring proof that those holy books are as divinely inspired as the bowel movement I had this morning.
