The texts reveal the idea of the sinfulness of people who incur the wrath of God by shameful behavior. As for the story of Adam and Eve, the whole world was created for them, and everything was permitted except one fruit. Despite their respect and love for God, Eve violated the rules and tricked Adam. Accordingly, God decided to expel them from paradise and punish them with suffering. Nevertheless, in the story of Noah, people were sinners, so they received punishment. Only Noah had true faith and appreciation for God’s principles. As a result, he had a spirit that saved himself and his family. Thus, the theme of sin and punishment for it, which in the modern world can manifest itself in the form of disease or failure, has been demonstrated in ancient works. Another theme is the reward for patience, an honest and religious lifestyle.
It is possible to compare the reads and the Epic of Gilgamesh. Both sources tell of the Flood that affected all of humankind. These stories share several common features, particularly the bird as a precursor for the extent of the Flood, the sacrifice, and the warning. It seems like they are describing the same event but vary significantly in details. For example, after a long voyage, the ark (according to the Bible) stops at Mount Ararat, but in the epos it stops at Mount Nisir (Kovacs, 1989). There is also a parallel with the story of Adam and Eve. The snake in the stories is a negative character and the reason for the loss of immortality. Although the prehistory of eternity is different — Adam was created immortal, and Gilgamesh obtained the flower of eternity, the analogy still exists. As for the third question, some of the long-term ramifications may be a reassessment of values, understanding that each of our actions leads to certain consequences.
