Contradiction with Genesis 8:22
This verse speaks of the continuity of seasons and cycles, including rain, as long as the earth endures, in contrast to Genesis 7:12 where continuous rain is presented as a unique, singular event.
Genesis 8:22: While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease. [While...: Heb. As yet all the days of the earth]
Paradox #1
Genesis 7:12 mentions rain lasting for forty days and forty nights during the flood. The contradiction here is the feasibility of continuous rain for such an extended period causing a global flood. From a meteorological and geological perspective, accumulating enough water to cover the entire Earth, including mountains, through rain alone would be impossible due to limitations in atmospheric moisture capacity and other natural processes.
