The Bible instructs that Noah took two of every "unclean" animal kind and seven of every "clean" animal kind onto the ark, for a total of approximately 6,744 individuals for roughly 1,400 animal kinds, rather than every single species.
Timeline of the Flood:
40 days: The period of continuous rain that began the flood.
150 days: The total time the floodwaters covered the earth after the rain stopped.
Day 150: The ark came to rest on the mountains of Ararat.
Total Duration: The entire process, from the beginning of the flood to the earth being dry enough for Noah and his family to disembark, took approximately one year and ten days.
The Bible does not specify the exact construction time of Noah's Ark, but common interpretations of the text, particularly Genesis 6:3 and the ages of Noah's sons, suggest a construction period of roughly 50 to 75 years or potentially longer, with some estimations extending up to 120 years.
All that in the bible grabs the imagination like the story "Journey to the Center of the Earth". Some believe it some don't, what difference does it make?
