Here is the website of one of the most respected Astro physicists in the World, Dr. Hugh Ross. His website is called "Reasons To Believe". I've personally heard him speak at two conferences in the last few years.
I am, an Old World Christian, and having that stand doesn't make me too popular with the mainstream evangelicals, but I really see a "head in the sand" philosophy with the other side. I still love my brothers and sisters in Christ, but must keep my lips tight in this area of discussion at times. Sometimes I don't.
He's (Dr. Hugh Ross) a strong Christian, yet believes that the earth is very old as revealed by scientific data, and scriptural evidences too.
Please check out Dr. Ross's fantastic website.
