Yep! The idea that a water molecule has always been on Earth is a really widespread notion.

You won't believe your eyes! WATCH as photosynthesis DESTROYS water!

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

    Apparently all water molecules on earth are recycled through life roughly every 2 to 5 million years.
