Why can elements be produced in the sun but not in earths atmosphere?

Elements can be produced in the sun through nuclear fusion reactions that occur due to the intense heat and pressure. These conditions are not present in Earth's atmosphere, which is why elements are not produced there. Earth's atmosphere primarily consists of gases and does not contain the necessary conditions for nuclear fusion to occur.
