Why is the earth big?
Why do we humans think, the earth is big?
Maybe because of...
... the physical size?
... the number of humans alive?
... the number of possibilities a human can do until his death?
Theory: The question depeends on which aspect of earth we use to compare.
For example, when we use money for comparision (given we have enough money to spend),
we could say the earth is big, because we can buy, whatever we wanted.
