Contradiction with Genesis 9:11
This verse indicates God's promise not to destroy all flesh with a flood again, contrasting the total destruction seen in Genesis 7:21.
Genesis 9:11: And I will establish my covenant with you; neither shall all flesh be cut off any more by the waters of a flood; neither shall there any more be a flood to destroy the earth.
Contradiction with Isaiah 54:9
God refers to the waters of Noah, promising not to flood the earth again, contradicting the complete annihilation described in Genesis 7:21.
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.
Contradiction with 2 Peter 3:6-7
These verses speak to the world being preserved for fire, contrasting the total destruction by water described in Genesis 7:21.
2 Peter 3:6-7: Whereby the world that then was, being overflowed with water, perished:
Paradox #1
One potential contradiction regarding Genesis 7:21 could be the question of divine justice. Some might wonder why a loving and just God would cause the destruction of almost all living beings. This could conflict with the idea of God's mercy and fairness to all creation.
Paradox #2
One possible contradiction is that fossil and archaeological evidence suggest a more complex and gradual development of life on Earth, while this verse describes a sudden and complete event that does not align with scientific understanding of natural history and mass extinction events.
Paradox #3
The contradiction in this verse lies in the claim that all life on land was wiped out by a global flood. Geological and biological evidence do not support the occurrence of a global flood that destroyed all terrestrial life. Fossil records, geological strata, and genetic evidence suggest a continuity of life through periods that would contradict such a complete extinction event. Additionally, the logistics of gathering and preserving species on an ark, as described, are considered non-feasible by scientific standards.
Paradox #4
The contradiction or conflict might stem from the idea of fairness and mercy. The verse describes a large-scale judgment leading to widespread loss of life. Some might see a conflict between this harsh action and the concept of a loving and merciful deity, raising questions about justice and compassion.
