In the Jewish and Christian Bible, Seth was a son of Adam and Eve. According to the Bible, all contemporary humans are descended from Seth through his great-great-great-great-great-great-grandson Noah. Seth was 105 when his first son Enosh was born, and he died at the age of 912.
In rabbinic literature, the name Seth (Hebrew: Sheth) is explained as meaning "foundation." According to this tradition, Seth was perceived as the "Foundation of the World," since he was the first person born of human parents and the ancestor of all mankind.
