Q about arguments for God's existence.

[Tonus]

Why are they all so fucking illogical and idiotic? Moreover, why are so many people dumb enough to be "persuaded" by them?

We tend to be pretty illogical in general, in that our subconscious controls a lot of our decision-making, and our subconscious can be very illogical. An example I've used before is phobias: the fear of something that we know in our rational mind is not a threat, but which our subconscious mind forces us to react to in irrational ways.

If our subconscious mind is convinced that god exists, no proof or evidence will be necessary; we will fashion it for ourselves however we can, using biases and other mental processes that screw up our perception of the world in many different ways (and not confined to religion, either). With that belief entrenched in our minds, the mental gymnastics appear far more convincing than they would if we were skeptical.

We cling very tightly to the things we think are true and to the things we wish were true, which is reflected in all kinds of behavior during our day-to-day lives. If people were logical and rational by default, there would be no lotteries, for example.
