I think I asked the wrong question for the answer I wanted but it still helped

 The question might be in trying to figure out how earth within 1 million years becomes mostly covered entirely with water?

If I imagine 300 mph winds blowing sand and rocks and sandblasting all the mountains of earth and eventually moving them into the oceans including the Himalayas, Alps and Andes and Rockies etc. around the world then maybe the oceans would be 8.6 kilometers deep worldwide.

This would be in Miles: 5.34379 Miles deep.

In other words with the present land blown into the oceans the oceans would still be 5.34379 miles deep worldwide which gives us the planet New Deva 1 million years into the future that is colonized then. But people didn't realize it was earth because all the lands were in the oceans then and only a few islands remained above water when they recolonized Earth and named it New Deva because they couldn't recognize it because of no land masses then even though their ancestors originally came from earth within the next 500 years forward from now and began colonizing the solar system and beyond.

This is what appears to happen to earth in the next 1 million years time.
