There is no specific description in the Bible that human beings have learned well after the flood. However, in the Bible, God tests human behavior and morality and punishes human crimes through floods and disasters. Therefore, it can be said that after the flood, human behavior and moral level have been improved to a certain extent.

However, whether human behavior and moral level have been comprehensively improved needs to be evaluated according to different cultural and historical backgrounds. At the same time, the flood disaster in the Bible is only an episode in human history, which cannot fully represent the behavior and moral level of the whole human being.
