The story of a great flood which was survived by an old man and a few others in a boat of his own making is not unique to any culture. There appear to have been several versions of it in ancient times. The most well-known of these today are three in number:
- Noah’s flood myth of the Bible (Hebrew)
- Matsya avatar myth of Hinduism (Indian)
- Flood myth from the epic of Gilgamesh (Mesopotamian)
