Here is a trillion dollar question: how did the oceans come to be?
It seems that there isn’t a universal consensus on their origin. There are diverse theories. “As Earth formed in a cloud of gas and dust more than 4.5 billion years ago, a huge amount of lighter elements, including hydrogen (H) and oxygen (O), became trapped inside the planet as the gases condensed and formed molten rock. Materials of different densities separated out; in the young planet’s molten interior, heavy elements sank and light elements rose. Gases rose through thousands of miles of molten and melting rock, to erupt on the surface through volcanoes and fissures. Within the planet and above the surface, oxygen combined with hydrogen to form water (H20). Enormous quantities of water—enough to fill oceans if it were liquid—shrouded the globe as an incredibly dense atmosphere of water vapor. Near the top of the atmosphere, where heat could be lost to outer space, water vapor condensed to liquid and fell back into the water vapor layer below, cooling the layer. This atmospheric coo
