Every human on Earth vanishes, except for one random person in the US. A button is placed on the summit of Mount Everest that can be pressed to undo this change. Can humanity be restored?

Every human on Earth vanishes without a trace, except for one random survivor: Ethan from the United States. Moments after the disappearance, a mysterious device materializes before him, displaying a message:
"Humanity can be restored. To activate revival, you must press the button housed at the highest point on Earth—the summit of Mount Everest."

Ethan essentially has as much of a prep time as he wants to gather all the essentials like food, water, weapons, vehicles and everything else that has been suddenly abandoned. He can raid supermarkets, libraries, military depots, and pharmacies for supplies. Ethan can still die of old age so this prep time isn't unlimited.

Now, Ethan faces an impossible gauntlet:
He must travel to Nepal and ascend to the summit of Mount Everest without dying.

Can Ethan survive long enough to reach the button and restore humanity?

His best hope is to go to Alaska and try to cross the bering strait if he somehow learns how to drive a boat.

Go find a few generators at Home Depot, and stock up on gasoline for the house.

Play a bunch of Flight Simulator then hop across the Bering Straight in a little Cub or Cessna and hope you learned well enough in the sim. I'd probably practice for 2-3 years with the best gear I could find at local game stores for the most realistic experience.

In 2-3 years most of of the gasoline will be useless sadly
