Why is there as much water on the earth today as there was thousands of years ago whjen dinosaurs roamed the planet?

first of all......
dinosaurs roamed the earth millions of years ago...not thousands...about 60 million years ago.
second
water is conserved...unless you have fusion or fission. Hence the equation, E=mc^2 mass is transferable to energy and vice versa
third
water can be added to our planet by comets since they are basically rocks with ice on them. (the trail of the comet is composed of dust and water)

Because there is no place for the water to go. It can't escape the Earth's gravity, and the cracks, and fissures inside the Earth are very limited, so it can't sink down.
BTW: The dinosaurs roamed the Earth 65+ million years ago, not thousands.

Quincy, you were doing so well till you said "water is conserved". No, water is merely the oxidized form of elemental hydrogen. With energy, hydrogen can be reduced into hydrocarbons. This process is called "photosynthesis" and plants do it all the time. Water can be taken up into hydrous minerals such as gypsum, micas and amphiboles. I just wonder where the evidence for the question came from. I certainly don't know of a method to allow geologists to determine how much (total) water existed in the past.

Where would it go?
Some escapes into space and some arrives via comet collisions.
