Creationism was the wrong approach by the Church to compensate for the scientific revolution. Nobody worth their salt argues about the scientific accuracy of the Greek Myths, but they understand that there are meaning and teachings to be taken from the stories. When you hear the phrase "don't fly too close to the sun", you understand that the story of Icarus tries to impart a lesson. You don't go around arguing about the scientific accuracy of the underground maze and the Minotaur. The stories in the Bible have roots that are much deeper than the year it was written (oral stories that were passed down before the written word was invented) and contain a collection of spiritual lessons that are lost today.
There's a parallel meaning behind the creation myths in genesis and the birth of the buddha. Buddha was born into a city built by his father, the king (God figure), who wanted to protect Buddha from the suffering from the world by encasing him into paradise (garden of Eden). He was provided all of his earthly needs and had all the evils of the world removed within the city walls. The only rule was that he could not leave the gates (don't eat from the fruit...ect). But eventually, the temptation of the outside world lures him out. He discovers the dark nature of being a conscious being by witnessing suffering and death outside the walls. What he sees from the outside world scares him into retreating into his paradise, but he is forever changed by the experience and can no longer be satisfied within (Adam and Eve unable to return to the garden once their eyes open). He leaves the gates and eventually realizes that suffering is the nature of reality as a conscious human being, and eventually becomes a Christ-like figure by reaching Nirvana through voluntarily suffering then accepting it was his duty to impart his knowledge to his fellow men. The old testament is a guidebook towards enlightenment. The creation myths were designed to teach us the nature of human consciousness.
