Why are there two Creation stories in the Bible?
The bible also contains stories, among others, of a talking snake that gives out dietary advice of doom, talking donkeys, magic knowledge trees, people turning into salt (watch your sodium intake), a man whose strength is proportional to his hair length, people magically levitating/whisked by magic chariot into the sky, virgin births and people reanimating after being dead for days (possibly, as a zombie). My point is it doesn’t really matter if there 2 or 100 creation stories in the bible as they are all myths, similar to Greek and Norse mythology.
The Bible is not the Word of God. It is a collection of writings written by men immersed in an ancient patriarchal culture. They all had agendas, whether it was keeping the social order, unifying doctrine, eliminating heresy or gaining converts. The Creation story is most likely borrowed from several cultures. The links below objectively detail the origins of the Bible (1) as well as the inconsistencies and inaccuracies (2) They are best viewed w/ IE.
