Primordial nucleosynthesis produced hydrogen, helium, and traces of lithium
Big Bang nucleosynthesis occurred in the first few minutes of the universe's existence.
Refined models of Big Bang nucleosynthesis align closely with observed light element abundances in the universe.
Elements heavier than lithium were formed later through stellar nucleosynthesis.
Example
Observations of light elements like helium and lithium support the predictions of Big Bang nucleosynthesis models.
