It was a simple question. The fact is that the amount of water on the earth is the same today as it was 4000 years ago or 4,000,000 years ago. If the ice caps were to melt and all the ground water were to be brought to the surface the earth would still not be flooded completely.
For that matter, water is continually arriving on earth in the from of cometary particles, so it is most likely the case that there has never been more water than there is today, which is still not enough to cover the globe.
Ok. Seems like you have all the answers. Good for you.
