Wasn't it already pointed out that the Earth does not spin at the RPM of a spun pizza dough nor is earth as malleable as pizza dough?
1.) Pizza dough doesn't spin constantly for 4.5 billion years.
2.) We don't know exactly how fast the earth was spinning in its early life.
3.) Much of the earth is liquid magma, dirt, sand, and water. Not exactly solid rock.
1) Given, but that doesn't seem relevant.
2) So... is there a possibility that the Earth began round?
3) Liquids are also irrelevant. If you spin a liquid really fast (like that of spinning pizza dough), like in a disk or blender, the liquid goes to the sides of the disk or blender. Inertia, I believe.
