[qs]But it isn't. Mt. Everest is five miles tall, has been that tall for quite some time, and will remain that tall long after we are gone assuming nothing blows it up.[/i]
But none of us was there so nobody knows exactly how long it's been that tall.
If the planet's surface were relatively level, the earth would be flooded twice a day as the tides covered it over. Since that doesn't happen, then it is apparent to all but the most casual observer that it is topologically impossible to cover the earth with water.
Note my hypothesis that there was much more water in the atmosphere then to create the vapor canopy and there were much smaller shallower oceans on earth. Overall then we could have had a lot more subterranian water as well as more atmospheric water with no direct sunlight. I know you're gona come up with the atmospheric pressure and all, but imo, the atmosphere was likely much higher with less density per sq in then. The canopy protection from the cold outer space would make up for the dimmer sun with no direct sunlight rays as we have today. Like in the winter in the North. It's those cold clear sunny days that are coldest. The cloud cover brings the warmer days.
To do that, you need to add water above sea level. But all the water we have is at sea level or below. Any water we take from the oceans will immediately flow back to the oceans. You can certain dump the water on the land, but you can't keep it there.
Gotta run outa town today so that's all I can say now.
