Contradiction with Genesis 7:20
While Psalms 104:8 implies the waters receded, Genesis 7:20 describes the floodwaters as rising and covering the mountains.
Genesis 7:20: Fifteen cubits upward did the waters prevail; and the mountains were covered.
Contradiction with 2 Peter 3:6
Psalms 104:8 speaks of the waters retreating at God's command, yet 2 Peter 3:6 references the world being overflowed with water as a previous destructive event.
2 Peter 3:6: Whereby the world that then was, being overflowed with water, perished:
Contradiction with Isaiah 54:9
This verse promises no more flood to cover the earth, yet Psalms 104:8 recounts the separation of land and water which seems to align with the flood's effects.
Isaiah 54:9: For this [is as] the waters of Noah unto me: for [as] I have sworn that the waters of Noah should no more go over the earth; so have I sworn that I would not be wroth with thee, nor rebuke thee.
Paradox #1
The contradiction in this context could be related to the description of natural phenomena, such as the formation of mountains and valleys. Science explains these formations through geological processes like plate tectonics, erosion, and sedimentation occurring over millions of years, while the verse might imply a more instantaneous or divine creation. This could be seen as conflicting with the scientific understanding of Earth's geological history.
