Zircon crystals provide evidence that the first ocean formed during the Hadean eon, between 4.4 and 4 billion years ago. Originally, there was only one ocean, because there were no continents to divide it into smaller parts. It was green because of the vast amounts of iron dissolved in it, until the first photosynthetic organisms created oxygen, which bound to the iron, creating rust that sank to the sea floor, leaving the oceans blue like they are today.
over 4 billion years ago, earth cooled enough so ''some'' steam became fluid. the small drops formed clouds. In the further cooling of the earth it has started to rain. The rain lasted for over thousands of years and all the watter formed seas and then oceans.
