* Hydrogen (H): The most abundant element in the universe.
* Helium (He): The second most abundant element.
* Lithium (Li): Present in very small quantities.
* Beryllium (Be): Also present in trace amounts.
These elements were formed within the first few minutes after the Big Bang in a process called Big Bang Nucleosynthesis.
It's important to note that heavier elements like carbon, oxygen, iron, and gold were not formed until much later, within stars through nuclear fusion.
