Well, I believe in the Bible and that includes Genesis. It is more a case of What Genesis is telling us than whether or not it is true.
The authors of the different creation stories in Genesis (and there are signs that it is at least three different tales, maybe more) had multiple purposes. The two tales though, Genesis 1 and Genesis 2, are completely different and frankly, the details in them are mutually exclusive.
The editors and redactors sat down and decided to include both stories, to place them in the order we see today with the younger tale coming first and the older tale second, to leave them in their original form and not edit them to take out the contradictions. If we are honest, we have to ask "Why?"
Why didn't the redactors and compilers smooth things out to remove inconsistencies and contradictions?
First, because the two tales show two entirely different and complementary views of GOD. The God in Genesis 1 is overarching, transcendent, aloof and powerful beyond imagination. She simply creates by an act of will; "Let there be Light", and there was light.
The God of Genesis 2 is quite different. The Genesis 2 God is far more personal, bumbling even, unsure, very hands on and personal. The Genesis 2 God is super-human, but something we can understand, relate directly with, communicate with.
Each story also tries to explain the world we live in. It does that as well as can be expected for the time. The fact that the Bible gets some of the science wrong is no more important than the fact that every theory and scientific law we use today will likely be shown to have been wrong. That is how science works. As we learn more we realize that our understanding of the mechanics was incomplete.
But the Bible is NOT about atoms, not about science. It is about mans relationship with GOD, GODs relationship with man, mans relationship with our fellow men and with the world we live in.
