Why were earths oceans originally green?

Because the Earth's first atmosphere/ocean system didn't have free oxygen, dissolved iron accumulated in the oceans, giving them a green color. As oxygen became available, it combined with the iron and settled to the sea floor to form banded iron formations (BIFs). Once the iron was "rusted" out of the water column, the ocean color changed from green to blue.
