Did you know the average surface temperature of the earth is around 60 degrees fahreheit? (15 celsius)

The circumference of the earth is about 24,900 miles around. That’s about 131,472,000 feet and would take you 88.66 days (2,128 hours) to run if you kept up the pace (11.7 mph) of the 2007 Boston Marathon winner!
And of course, you’d need to be able to walk on water too, as you’d have to cover some of the water that covers about 70% of the surface area of the earth.

Speaking of water, there are an estimated 326 million cubic miles of water in the rivers, atmosphere, oceans, groundwater, and other places on earth. Each cubic mile of water is an astonishing 1,000,000,000,000 (one trillion) gallons of water, making the total amount of water 326,000,000,000,000,000,000 gallons. While I was looking for the info on how many zeros this figure would contain I found this table of zeros to number names (the above figure is 326 quintillion). Why not check the table and find the highest number you know and then learn the next highest one? It’s not worth it to me to memorize the whole table up to a centillion (303 zeros), but it can’t be too hard to just memorize one more.
