Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.

They are formed inside of stars.

Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.

Chemical elements are formed in the Universe by stellar nucleosynthesis.
It is believed this was how the universe formed. Hydrogen fuses to form all the other heavier elements on the periodic table up to Element number 92
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
Elements heavier than iron are formed in super-nova explosions.
Once the Universe got cold enough, atoms could form. It is believed that in the Big Bang, only hydrogen, helium, and small amounts of lithium formed; all heavier elements were formed later, through fusion in stars.Once the Universe got cold enough, atoms could form.
