Can enough pizza dough be made to cover the surface of the earth?

Some friends and I are having a debate as to whether enough pizza dough could be made to cover the surface of the earth if you had access to all of the flour in the world.

804 billion pounds of flour are produced annually.

Every pound is 453.5 grams.

You need 312 grams of flour to make a 16 inch pizza.

A 16 inch pizza covers 201 sq inches.

The surface area of the earth is 7.93*10^17 square inches.

Can enough dough be made to cover it?
