I think the earth might have gotten folded and pushed up due to runaway subduction of the continental plates (Google: John Baumgardner Ph.D. geologist for more info).
The earth might also have been raised by volcanic inflation of underground magma. In 1902 when Mt. Soufriere on St Vincent erupted killing 2,000 there were areas where the sea level of the shoreline changed 15 feet over several days. When Pelee on Martinique erupted the next day killing almost 40,000, a ship many miles at sea had the following experience. It became very hot, and sharks started leaping out of the water all over the place. Then the water under the ship suddenly dropped about 4 feet. There must have been extremely widespread disruptions on the sea floor and the underwater ground level.

You are on the right track, if you read “The 12th. planet” by Z. Sitchin you will likely get a good understanding of the origin of our planet and the formation of our solar system
