i read somewhere that if the solar system got filled with oxygen, the planets would first stop spinning cuz of friction (that and then everything would fall onto the sun or smthng) but oxygen already exists on earth, so how is the earth still spinning?

Friction only creates a force when the two materials experiencing mutual friction are moving at different speeds or in different directions. The earth and its atmosphere are orbiting around the sun together at the same speed and in the same direction.
