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?

All the books in the world can't replace months and years of experience that are typically required for a solo transoceanic trip. So yeah, you're on a time crunch, with A LOT more to do and learn and train and plan for than time allows.

And that's just to get to Nepal! We haven't even approached the issue of what to do once there. When is the last time, if EVER, someone handled a base to summit solo expedition?

You can do Africa to Europe in under 9 miles of sailing

North America to Russia in 2.5 miles.

Edit: with both of those examples you also don't have to have any navigation skills at all, you can see your destination at all times if you leave in daylight

Unless you start in Australia/new Zealand or on tiny islands like Vanuatu almost anyone would be able to cope with the sailing!
