“If you placed the entire world population in Texas (please don’t), everyone would have plenty of room.”
Why not? You just said everyone would have plenty of room. Define plenty of room. Ten square feet?
Texas is approximately 1 million square miles or 2.787e+13 square feet. Divide that by 7 billion folks (give or take), and that leaves almost 4000 square feet per person.
It's an empty, lonely, world, outside of citites.
Math is hard, for some folks.
