There are many flood myths across different cultures. These stories often share similar themes, though the details may vary.

 They usually involve a divine being who decides to flood the world because of human wickedness, a single righteous person or family who is warned of the coming deluge, and a means of survival that typically involves building a boat or a similar vessel.

Cause of the Flood:

 Both stories attribute the cause of the flood to divine displeasure with human wickedness. In Greek mythology, Zeus decides to destroy the Bronze Age due to the wickedness and impiety of men. Similarly, in the biblical account, God decides to flood the Earth because of mankind's evil behavior.

Hero's Forewarning:

 In both narratives, a divine entity provides the protagonists with a warning about the upcoming catastrophe. Prometheus, Deucalion's father, warns him in the Greek story, while God directly warns Noah in the biblical account.

Survival Mechanism:

 Both stories involve the building of a structure to survive the flood. Deucalion builds a chest based on Prometheus' advice, while Noah builds an Ark following God's instructions.

Post-flood Promise:

 After the floods recede, both Zeus and the biblical God make a promise never to destroy humankind by a flood again.

Repopulation:

 Both stories also involve the repopulation of the Earth. Deucalion and Pyrrha repopulate the Earth by throwing stones over their shoulders that transform into people. Noah, his family, and the animals that survived in the Ark repopulate the Earth in the biblical narrative.

Hero's Reward:

 Both heroes, Deucalion and Noah, are rewarded for their piety and righteousness. They survive the flood and become the ancestors of the new human generations.

 These similarities reflect common themes about divine justice, human survival, and the rebirth of mankind that are prevalent in many cultures' mythologies and religious texts.
