Hmm! So if the land mass is spreading and expanding to such an extent and the volume of the earth has gone from a tennis ball to a basketball, where has the water come from that it now covers most of the globe.? Assuming it was inside the earth so that when the 'cracks' appeared it came to the 'surface'? if so, what replaced the area where the water came from?
With all the heat from the compression of the earth land mass, surely steam would have released it to the atmosphere? So., if the atmosphere was full of steam and vapour from the compression., and the land expanded. There has to be a void!
Does this leave room for the hollow earth theory?
And by the way, what stops the water from rushing back into the void., gravity?
Gravity has always been there! Oh, the questions..., the questions, but rarely the answers!
