The Creation account in Genesis conveys a number of Truths.
Remember that at the time it was written the level of human scientific knowledge was basic or non existent so a scientific account intelligible to the Einstein generation would have been useless.
Genesis tells us that God exists, true; that God created the universe and everything in it out of nothing, true: that God specifically created man and woman and charged them with increasing and multiplying and populating the earth, true.
Genesis tells us that Adam and Eve possessed free will and alienated themselves from their Creator through an act of disobedience as a result of which their previously begnign environment became hostile. We still live in this hostile environment amidst, pain, suffering, sickness and death, true.
Discussion in a combox cannot accommodate the whole exegesis of Genesis.This is just a bare sketch of theTruths contained in Genesis, Truths which the Church has continually taught and still teaches today.
