As far as I am concerned there are just two explanations for the world and the universe as we know it. Only one of them can survive logically.
1. God is eternal and all things proceed from Him.
2. Matter is eternal and all things proceed from it.
Whether you believe in the first or the second, both need a good apologetic (reasoned defence) and the logical ramifications of each need to be carefully examined and worked through.
If you are an atheist, non-Christian or a Christian reading this post, have a look at the six questions and give them some serious thought.
