IOW, they don't prove what they set out to prove, as far as Kant is concerned - he really didn't save them from Hume at all, so much as just saying they were going about it all wrong anyway.
Anyway, I've never been enamored of Kant much, myself. I'm more of a strict rationalist - what a surprise, huh? ;)
OTOH, if more people took a Kantian view of God, there'd be much less conflict between science and religion to begin with. A God that immunizes himself from reason in the first place has little to fear from logic and reason ;)
You are really good at misrepresentation. It is evolutionists that are trying to prove God does not exist through science, and have been doing so for some 150 years. Christians are just trying to disprove that lie. Kant's criticism just showed that you cannot prove or disprove the existence of God through philosophy, it did not disprove the truth of either Aristotle or Aquinas. However, he did disprove Hume's materialistic view of the world very decisively and that is why you do not wish to expose Hume's statements to examination.
