Because hydrogen is the most abundant element in our universe.
hydrogen,All stars are composed primarily of hydrogen. Stars can also contain some other elements such as helium, but hydrogen accounts for the majority of a star's composition.
Hydrogen is the most abundant element in the universe due to its simple atomic structure and presence in stars. Scientists observe hydrogen through its spectral lines in the light emitted from stars and galaxies, confirming its widespread existence. Additionally, studies of cosmic microwave background radiation and the chemical composition of various celestial bodies provide further evidence of hydrogen's presence.
The most abundant element in the universe is hydrogen.
Hydrogen is the most abundant element in the universe and is the primary element that is burned in stars, particularly in the process of nuclear fusion to form helium.

Hydrogen.
Stars contain hydrogen, helium and a little iron.
Hydrogen and helium are the most abundant elements in stars.
The original element is hydrogen. All others were synthesized ("cooked") in the interiors of stars, after the stars contracted out of clouds of hydrogen.

Stars are mostly made up of hydrogen. The stars use the hydrogen atoms to make helium. Please recomend me.
