The word water sounds like hudor the root of the word Hydra the multi-headed water monster of Greek mythology, and atl sounds like water (and otter) if you make the r sound like the letter l, so either Atlas was named for the word water or vice versa, a mystery because Atlas was a great grandson of Ham yet perhaps he (Atlas) procreated with some Indo European women (progeny of Japheth) for his name to then be associated with water, so water having been named for him.
