Comets & asteroids over billions of years.

also, deep within the mantel there are minerals like ringwoodite that at some point during their life decay and under the right circumstances form H2o

If you mean originally, we don’t actually know. The current theory is that it’s from frozen meteors putting space ice onto our planet over billions of years.

Might need to define “the water”. The water on earth in general? The water out of your tap, water as a substance?
