  1.  @EGYong-sj3cc  No, we do know quite a bit of what was on this planet 780 thousand years ago and no, it wasn't a shapeless rock. Please educate yourself. A million years is nothing in geological scales. We know quite a bit of what was on the planet even a million million years ago. The solar system itself is around 4.8 billion years old. Again, please educate yourself.
