To carry a single raisin to the top, then he climbed it a million more times to bring more raisins, then he made a jet engine from the raisins. Then he started bringing more raisins so that he could make a raisin plane for the amazing raisin engine.
In the intervening thousand years, other climbers learned to cybernetically modify their bodies to be able to climb every rock face on the planet. The resulting boom in cybernetic technology granted immortality and immunity to all diseases to humanity. Humans never did master the raisin jet though (because they learned to transfer their conciseness over the internet so honestly jet engines seem kinda silly).
