Some climbers found the corpses of five elephants halfway up Mount Everest. They died trying to reach the top. How the hell did they get there?
Do not wonder how they climbed the mountain. Wonder why they tried. Because elephants are clever- unusually so. They can sense the seismic sirens of an oncoming disaster, at which point they retreat to higher ground.
Mount Everest is the highest ground there is.
Do not consider the impossibility. It will not consider you.
Do not ask how the elephants got there.
Ask yourself what the hell they were running from.
