Are you saying the Flood as recorded in Genesis did not happen?
Good question.
Whether the flood in Genesis 7:7 (easy to remember that number) is fact and happened? I hope so. If yes, then God’s message is loud and clear. If not, then the message of the rainbow still stands.
I accept St. Peter’s interpretation of the message. “This water symbolizes baptism that now saves you” (I Pt 3:21).
Noah’s water is possible.
Baptism’s water is necessary.
Keep up the good work.
