My deduction is that a creator must exist and that He has communicated in some manner. Prophecy and miracles are the evidence of His existence outside of time and space.
I’m writing from the perspective and assumption that the Bible is divinely inspired; but that implies it must be internally logically consistent.
There is a lot of evidence that contradicts your claims. However, people believe what they want regardless of the evidence.
