Jonahdog,
Your arguments in this thread are historical in nature. You claim "why believe what a bunch of old guys cooked up centuries ago" (paraphrased)? Yet, many accept the historical analysis of ancient texts without question. Such as Hammurabi's Code. We accept that it is a code of law, established from various historical and archaeological evidences. The same with Mayan histories. Even ancient Greek histories. So why not accept the single most accurate, written closest to the events of its happening, archaic historical text in the world? Secular sources make the same claims that are made in the Bible. Roman soldiers' letters detail the exact same events as found in the Gospel according to Luke and Acts (Luke being a Hebrew Historian).
Have you ever examined St. Thomas Aquinas' "Five Ways?"
In my opinion, it does a sufficient job of addressing basic arguments as means of proving God's existence. As I stated in a different conversation with you, the argument for God's existence is not a purely scientific one; as science can only explain the natural, and God exists beyond the natural realm (supernatural). One can only proceed with logic and reason, utilizing natural examples (history, archaeology, biological, chemical, etc), to point to or negate God's existence.
