When the Earth's continents were all together in a single land mass, there was only one mass of water on Earth and this would not have produced the amount of tidal friction we see today when the Atlantic and Pacific Ocean are on opposite sides of the globe. This causes their respective tides to set up harmonic forces which have a larger effect on the tidal friction applied to the Moon. All other elements are created in the titanic explosions of supernovas. The energy comes from the gravitational collapse of a massive star after it uses up its hydrogen fuel supply and can no longer support its own weight via the expansive forces produced by the burning of that fuel. A few more questions.
Chemistry shows how elements combine to produce different things.
Biology is the study of how living things live, die, and reproduce. Current theory says that universes are being created all the time. Only those whose creation produces the proper mix of forces and constants will end up producing universes which can support the same sorts of things that we observe. Other universes may also be able to support life, but the life in those universes would be quite different from that found in our universe. Obviously, we only know the universe in which we live and, if our universe wasn't the beneficiary of certain random events, it wouldn't be as we observe it.
