"....i think that most people start from their own position presupposing certain things,..."

pete..."their own" does not necessarily refer to a personal one. If one accepts and adopts a basic set of rules set out to describe a well organized system, it is not exactly ones "own".

Belief in the Bible as literal truth is certainly one such system, as is 'scientific inquiry'. The basic difference is that the former is 'locked into' one basic set of assumptions and thus, a very limited set of conclusions; whereas the latter demands constant reassessment of both assumptions AND conclusions. IF science makes mistakes, its own rules provide for course correction. The theology which defines creationism as 'correct' from the beginning cannot really even look at other answers...except to think about ways to deny them.

These are not just 2 different opinions, such as having favorite colors, but entirely different ways of thinking. I always claim that IF there is a God who gave us the ability to see different possibilities, he/it would expect us to 'think' rather than just nod in agreement to opinions handed down over the centuries by OTHER humans who were just as fallible as we are.
