The prevailing theory is that water came frome " water babies", or meteors and debris from the kuiper belt, during the formation of the earth. The metoeors are said to be compsed mainly of water ( in ice form). I don't buy it. That is way too much bombardment, considering the amount of water on earth today.
Great Question, because nobody can say for sure , it is a topic that needs more thought . I think the Expanding Earth Theory explains a little about this.

Water i's just a combination of elements. Water is made of Hydrogen and Oxygen, which are two elements present throughout the universe. In the earth's case, they combined in such a way as to result in the substance we call water, when the earth was formed.

The ultimate source was mostly oxygen formed in stars and exploded into space. The hydrogen has always been around, since the Big Bang first cooled and formed matter.

the current theory in geology is that the water on earth was brought here by comets that hit the earth a long time ago.
