Question
I teach Torah to some women from different backgrounds. As we study questions come up as to how do the Rabbi's and sages know what happened during Adams time and Noah's time? The particularly question stories about the soul preexisting and for what reason HaShem created the world. Things that are not specifically in the Torah. Some women have come out of catholic backgrounds.

Question
Did the flood in Noah’s time cover the entire planet with water and wipe out all civilization and animals? Or did it only affect the geographic region covered in the Torah? Were the Chinese, Native Americans, and Aborigines (just to name a few) affected by the flood? Or just those in and near the Middle East? Did Noah take all animal species from all parts of the world on board the ark, including kangaroos and llamas, for example? Or just those animals found in the biblical region?
