This is not the normal path that those who come to question creationism take. The stereotypical student who comes to reject the fundamentalist view becomes a questioner through considering scientific evidence. However, my doubts were born from studying Scripture! Genesis is so much richer and deeper than the bare literalist explanation. The creation narratives also fit within a larger work, the Torah, an interpretive context that most fundamentalists fail to consider adequately.
Now, esteemed scientist and believer Francis Collins has established a foundation with an excellent website that attempts to provide an alternative to the culture war approach of both atheistic and Christian fundamentalists. It's called BioLogos, and here is its mission...
The BioLogos Foundation promotes the search for truth in both the natural and spiritual realms, and seeks to harmonize these different perspectives.It is a well-designed and well-written site that seeks to answer many of the questions that arise when one tries to take both the Bible and science seriously.
You can also check out the blog that complements the site at Science and the Sacred.
Highly recommended, even if you don't agree. BioLogos is a fine example of thoughtful, careful, and irenic scholarship.
