The Idea
All water on Earth came from space (Earth can not produce water).
For bacteria to create life shallow, warm waters are ideal so may have been little water then.
Over Millenia Earth came in contact with the glacial meteor belt slowy raising the water levels and allowing the abundance of life to grow.
Maybe 65million years ago earth was hit by glacial meteors in gigantic proportions, not one large asteriod but wave after wave of glacial meteorites.
This could have opened up a catologue of events, (maybe one large one did hit mexico that was too large too melt on entry?)
1. The Earths mass got larger increasing the gravity fundamentally so giant dinosaurs could not exist.
2. The pressure of the oceans and the increased gravity start the movement of the teutonic plate causing continental drift.
3. The increased gravity pulled Earth into a new orbital cycle away from the glacial meteor belt.
I am sure there are many reasons why this theory is wrong but I welcome your thoughts.
Thanks
