Why arent two hydrogen atoms bonded together considered a compound

Since at least two elements form a compound, and here we have only one. And we have two hydrogen atoms bonded together in this situation, so we have a bond, so there's just one element, and in order to have a compound, we need to have at least two elements.

Explanation:

It's because Hydrogen gas is a molecule, but not a compound because it is made of only one element. And Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms.
