That is -- evolution is just a *theory*. The Holy Text and Revelation -- those are Truth.There is a hypothesis that teh Bible is the word of God. But, since it cannot be validated or falsified, it remains a hypothesis and cannot be elevated to the level of a theory.
Two straight lines parallel at one point will remain parallel at every other point, and never cross. That is a basic postulate. 1 + 1 = 2, another postulate. Postulates are where you start from, they are the base around which a system of logic or proof is built and yet they are truths "outside" the proof-system.
The Holy Text and Revelation at Sinai are not hypotheis nor theory, they are Primal Truth.
