The real question is... Is it possible to prove something exists ?
Probably not. There's the additional problem of what the word 'exists' means. It seems to me that fictional characters like Sherlock Holmes, and abstract things like numbers and mathematical structures, or the laws of physics for that matter, don't exist in quite the same way that the tables and chairs do.
In everyday life, we don't use arguments to prove something exists.
We use them more rhetorically, in hopes of convincing our readers to believe what we are saying. Which might include a proposition like 'X really exists'.
In any case, to conclude "God Exists", doesn't tell you very much about God.
'God' is even less clear than 'exists'. That's why I say that I'm an atheist regarding the deities of the Koran, Hebrew scriptures, New Testament, the Gita and similar things. But I'm an agnostic regarding the metaphysical functions that natural theology often associates with the word 'God' such as first-cause, source of the universe's order, ultimate unreducible level of existence and so on.
It doesn't tell you that weekly donations will ensure a good place in Heaven.
Right. Religions typically prescribe things for people to do. Those things don't typically follow from the religion's definition of deity, provided that the religion even has one. (Non-theistic religions exist.)
I think it is a mistake to try to prove God exists.
I don't think that it can be proved, in an apodeictic sense.
But, if believers want to convince non-believers like me to believe the same things they do, they will have to provide me with some convincing reason why I should. That's why I say that it's more of a rhetorical matter.
It is easy to find fault with any one of the arguments.
Yes.
Having found a fault, a person is likely to start having doubts.
Certainly if their faith in the religious doctrines is dependent on their faith in those particular arguments.
These doubts might lead to further (dangerous) investigations.
I wouldn't call them dangerous. Certainly not if one's objective is to continue learning. It might be dangerous from the perspective of a belief system that isn't entirely confident of its ability to hold the allegiance of its more intelligent followers.
For example, they might start comparing their religion with other (evil) religions.
I don't think that Judaism or Christianity (including 7th Day Adventism) are the best religions, ethically, intellectually or factually. So people becoming motivated to seek more widely is probably a good thing.
I think it is best to stick to traditional methods of saving souls.
Regular indoctrination of the true religion from birth is effective.
Propper ducation is also impotant.
Teaching atheist science must be discouraged.
I couldn't disagree with you more.
