The matter that came out of the Big Bang was about 90% hydrogen and 10% helium.

Hydrogen and helium were the two main elements created in abundance during the Big Bang nucleosynthesis. These elements were formed in the first few minutes after the Big Bang, when the universe was hot and dense enough to support nuclear fusion.
Hydrogen was formed in the early universe through a process called Big Bang nucleosynthesis, where protons and neutrons combined to form hydrogen nuclei. It is the most abundant element in the universe, created during the first few minutes after the Big Bang.
Elements are Elemental, you "cannot" create them, they were already here. Man has created many alloy's & composites, but man has never created an "element". This all occurred micro-seconds after the big bang.
Hydrogen is considered the primordial element in the universe because it is the most abundant element, making up about 75% of the universe's elemental mass. It is thought to have been the first element to form after the Big Bang, leading to the creation of stars and eventually heavier elements through nuclear fusion processes.
Hydrogen was formed in the early universe, around 3 minutes after the Big Bang during a phase known as Big Bang nucleosynthesis. At that time, the extremely high temperatures and pressures allowed for the fusion of protons and neutrons to form hydrogen nuclei.
Hydrogen is the most abundant element in the universe, making up about 75% of its elemental mass. It is formed primarily during the Big Bang and powers stars through nuclear fusion. While it may not be rare in the universe, it can be challenging to isolate and use on Earth.
