Where do elements come from

Elements of the world came from hydorgen gas which is in clouds. The universe is about 95% hydrogen. CLouds of hydrogen gas and dust are comprssed by gravity into stars, which, by the process of nuclear fusion,change a one-proton hydrogen nucleus into a two-proton helium nucleus. Elements came from the nuclear fusion which take place at the cores of stars. The nuclear fusion in the stars also is a bug reason why there are elements here on earth. All Liquids,gases, and solids found on our planet are made from or more of 92 naturally occuring elements. From what they have observed, scientists have determined that these same 92 elements are found throughout our universe. This suggests that a common process leads to their creation. Elements come from a lot of things that go around the world.
