      The best, and widely accepted theory, is that the Earth formed about 4.5 billion years ago, along with the rest of the solar system. I can describe the process in more details if you are interested, but in short, there was a huge, huge cloud of gas and dust which contracted on itself and formed the Sun and the planets (and all the rest of the solar system stuff). All the elements that are found on Earth and in the Sun and in the rest of the solar system, come from that original cloud.
