water from space

Earth got its water from space. That is what science say. Yeah, asteroids brought the water in. Well, we do not believe that one. Like there is a lot of sodium in our sea. Asteroids do not contain much sodium, but even if the water was pure. There is too much sodium in our ocean. Fact is, the earth cannot be more than 40 million years old due to sodium levels now. Calculate the amount of salt going in. Please add the amount of rain. Hey, it does not add up.
