The simplest answer was that it was a cosmic event - when the planet was created, the gases on this section of this universe just cooled off in such a way to make a planet that had more water than land. It did not happen immediately but took millions of years for it to cool off and create the planet that we know. If Earth did not have as much water, maybe it wouldn't be able to support life as it does now. The precise balance of land and water resulted in a planet that was able to support life.

What are terrestrial ecosystems?
Ecosystems that are established on land (as opposed to Marine ecosystems).
Are ecosystems with a lot of water support fewer organisms than ecosystems with little water?
No, just the opposite. Think of an ocean compared to a desert. Which has more life in it? Even IN a desert, where is there more life, in the dunes or at the oasis? Water is necessary for all life, creatures that can survive on minimal water are actually rarer than other forms.

What is a land based ecosystem?
