6 Billion People

6,000,000,000 (billion) is 6000 millions.

OR

6 million thousands.

UM football stadium holds 100,000 people(and then some). It is the largest college football stadium in the country.

The people of the world could fill the stadium 60,000 times.

Oddly, the land area of the world turns out to be just short of 60 million Square MILES, not all of it habitable, as is the case with Antartica, and the peaks of very tall mountains. Nevertheless, that translates to an average of 100 people per square mile. Taking more realistic numbers, Antartica out of the equation, a wild quess of twenty percent of the rest as uninhabitable, gives a figure of roughly 140 people per square mile. Each of us could, theoretically have the 199,131 square feet of space, or a spread that was 446 feet by 446 feet, about a football field and a half on a side. Hmmm.
