Here's how it happened:
* The Big Bang: The universe began as a incredibly hot and dense singularity.
* Expansion and Cooling: As the universe expanded and cooled, the energy began to transform into matter.
* Formation of Protons and Neutrons: The initial energy transformed into fundamental particles, including protons and neutrons.
* Hydrogen Formation: Protons and neutrons combined to form the first atomic nuclei, primarily hydrogen (one proton) and a small amount of helium (two protons and two neutrons).
So, the hydrogen we see today was formed in the earliest moments of the universe, billions of years ago.
