Charles Ellicott Commentary Psalms 24:2

"For he hath founded it upon the seas, And established it upon the floods." — Psalms 24:2 (ASV)

Upon the seas.—For the idea of the earth resting on water, compare Psalms 136:6; Proverbs 8:25–29. In Genesis, the dry land emerges from the water, but is not said to be founded on it. In Job 26:7, the earth is said to be hung upon nothing. The idea of a water foundation for the earth naturally grew out of the phenomenon of springs, before it was scientifically explained.
