Answer 1

Megalodon is an enormous coastal, surface dwelling shark and most of the unexplored ocean is in far remote areas where there is basically nothing there but water so it’s pretty safe to say we would definitely have seen one if it were to be swimming around. We also have the knowledge that giant size predators have been lost in evolution in general due to the fact it is just not feasible to meet the dietary requirements of giant carnivorous predators. Great question though
