Hydrogen is the most common element in the universe as a whole; about 75% of the universe by mass is hydrogen (since hydrogen is also the lightest element, that means that the percentage by number of atoms is even higher) . Helium is second; oxygen is a fairly distant third.
Hydrogen and helium are the first elements produced in the universe after the big-bang.
The vast majority of matter in the universe is in the form of Hydrogen and Helium.
Hydrogen is the most abundant element in the universe.
When hydrogen and helium atoms first formed in the universe, the temperature ranged from about 3000 to 4000 Kelvin. This temperature allowed protons and electrons to combine to form neutral hydrogen atoms, a process known as recombination. Subsequently, the universe became transparent to radiation for the first time.
From stars.
Hydrogen and helium are the two most abundant elements in the universe.
By mass, hydrogen = 75%, helium = 23%.

No. The hydrogen in the universe was formed during the Big Bang. Stars consume hydrogen, fusing it into helium.
Because in our universe they are the simplest.
The vast majority of matter in the universe is in the form of Hydrogen and Helium.
Hydrogen and Helium gases make up the universe.
