Antediluvian

In Christian mythology, the antediluvian period is the biblical period between the Fall of man (when, at the beginning of time, in a magical garden, a talking snake convinced a man and woman to eat some fruit, whereupon the creator of the universe decided to abandon the garden and sentence humankind to death) and the flood (the moment when god decided to start over with mankind and drown everyone except a man called Noah and his family).
