> got to nuclear power and destroyed the planet resetting civilization
don't even know why they need to get that far. we already know the younger dryas was a time period of extreme climate swings and natural disasters with purely natural causes. a civilization existing before that time could have been advanced without needing to have achieved nuclear. plus its pretty trivial to prove that no prexisting civilization made it to the fossil fuel era. never-mind NUCLEAR age.
