Which makes me wonder if the land/sea areas are reversed from where they were in the past. Which could mean that there are entire civilizations lost under what we cal the "ocean" now.
One of my favorite subjects! Our MotherEarth, the little blue spaceship, now hurtling through space at around Mach-57, while spinning at Mach-1.3... where did she start and when? (4 billion years best estimate; this universe, 12 billion)
The rock record and 600,000 year old ice cores give us a lot of clues. The early air samples trapped in the old ice are quite informative.
The very old maps that show the actual coastline of Antactica, which has recently been confirmed by satelite, likely not always so barren. The record also indicates that the current continets came from one larger, older, main continent.
The many geographical shifts of the poles and the outright swapping of north for south as shown by the rock record.
The many different sea levels and uplifting of land areas... some quite recent. (There are parts of Cuba where you walk among cactus and coral on the trail down to the coastline)
So, when the poles swap... is it the skin that shifts, or the molten core?
What happens to old stars that simply burn out? Could they cool down and become havens for life, captured in another star's gravity?
Yes, i believe that very advanced civilizations have thrived here before, then gone... why not Atlantis?
