Best Evidence Yet That Comets Delivered Water for Earth’s Oceans

It seems that comets might have delivered Earth's water after all.

70% plus of Earth covered in water with an avg depth of about 1000m. 1,260,000,000,000,000,000,000 or so litres.

The Late Heavy Bombardment must have been pretty damn heavy to deliver all that water.
