Evidence for God:
1) Cosmological argument: if you accept the fact that everything that begins to exist has a cause, then since the universe began to exist (per the Big Bang), it must have a cause. The first premise ("everything that begins to exist has a cause") may sound like bs, but really, it's as inductively likely as anything established to be true by a science, since I can provide a buttload of things that begin to exist that have a cause, whereas I can't think of any that begin to exist that don't have a cause. The argument turns on whether or not you're OK with the idea that things that don't begin to exist have a cause, but I think this is a reasonable claim to assent to, because otherwise you have infinite regress (x caused the world, y caused x, z caused y, a caused z, b caused a ad infinitum).
So, I tend to reformulate the argument like this: something has to be eternal. According to the Big Bang Theory, that eternal thing isn't the world. So it's probably an immaterial (since matter was created/began to exist at the Big Bang), extraordinarily powerful (since it created the world out of nothing, or at least nothing material), and eternal/atemporal being. An immaterial, incredibly powerful, eternal being pretty much fits the bill for "God".
2) Teleological argument: basically, intelligent design, but it has to do with stuff like how earth is a certain distance from the sun, the sun is a certain type of star, the cosmic background radiation is a certain wavelength, gravity is of a certain strength, etc., and without all this stuff, life couldn't exist. The probability of this happening randomly is fairly low, so it seems likely that there is a God that made all these things happen in this precise way.
3) Moral argument: alright, this is where the foundational bit comes in. If you believe in objective morality, there has to be an objective standard for that morality. But where does the standard come from? It can't come from individuals, because then the right thing to do is whatever each individual thinks it is (solipsism). It can't come from cultures, because then the right thing to do is whatever each culture does (cultural relativism). This might seem to be okay, until you remember that this means that slavery in the United States, the gladiatorial games in Rome, this practice, known as widow-burning, are all okay because they were sanctioned by the cultures where they took place, to say nothing of Nazi Germany. So, what standard can there be for morality besides people and society? Maybe you could argue the earth as source for morality in some way, but then you get into arguments like "it is the law of the earth that the weak dominate the strong; I am strong; therefore I am justified in dominating you who are weak." So, it seems likely that there is a source for morality that transcends the individual, culture, and the world. This would appear to be God.
4) Ontological argument: somewhat bs argument, but some thinkers have argued that God is true-by-definition, because God is that of which no greater can be conceived, and since it is greater to exist than not to exist (existence is a perfection), it follows that God must exist.
Side note: people try to counter that argument with the "perfect island" or "perfect unicorn" argument, (a perfect unicorn must exist for the same reasons as God must, according to this argument), but that is a terrible counterargument, because, quite frankly, that perfect unicorn would be God, and would not have all the properties of a unicorn. For instance, it is one of the properties of all things that have physical existence on earth that they come into being and go out of being. One could argue that if one did not have this property, one could not be considered a thing with a purely physical existence on earth. So then the "perfect island" has a characteristic that islands cannot have, insofar as the "perfect" island would not be generated and could not be destroyed. Also, islands and unicorns both have defined physical limits, can move at finite speeds, etc., and both of these things seem like they would not belong to the greatest possible being. So yeah, that counterargument is crap.
Some random other stuff:
-Descartes and Augustine both think that the only proof that we are not in a matrix-like situation is a benevolent God who would not want to deceive us.
-There's a guy named Alvin Plantiga who has a book called "God and Other Minds" that argues that we have as much reason to believe that God exists as we have to believe that other people have minds.
-Historically, there's the problem of the transformation of the disciples, how and for what reason the disciples stopped being afraid of their hostile governments and started building the Christian church. This only works if you accept the account of the Bible, I suppose, but there are more manuscripts of the Bible closer to the original date of production than any other ancient document, for what that's worth.
-Regarding Nietzsche, I dunno really. It's just that he has this vision of the world as, essentially, the strongest survives, lets quest after that which most enlarges life, i.e., the pursuit of glory, the pursuit of permanent achievements, etc., all regardless of morality. He would laugh at the idea of the special olympics, because for him it's absolutely uproarious that we would celebrate a group of people for being "good" at something when they are all, relative to the non-special olympics, very very bad at all of those things. This is the world without God, because the best thing after God is human life, but without God there is no obligation for someone to protect anybody else's life, rather than pursuing the fullness of life for themselves. Also, while many people pretend to be perfectly fine with the idea of personal extinction being the end of life, as Nietzsche and all of the existentialists after him realized, it causes hella problems with the meaningfulness or lack thereof of life.
-Also, if you want to see the same arguments presented in a better form than I know how, you might look up these people: William Lane Craig, Alvin Plantiga, Richard Swineburn, and maybe even David Bentley Hart and his book "Atheist Delusions".
Technically, I agree with this. I don't think you can establish fully rationalist proof for anything. But I don't think God is any less reasonable to believe in than anything else, and some people think that God is less reasonable to believe in than what is available to their senses, which, from a rationalist perspective, is 100% wrong, since we can't furnish any proof for the veracity of sense experience, and certainly not any scientific proof.Speaking as someone who has a strong personal belief in the existence of God...there exists no indisputable evidence for God or any objective evidence that would and could be recognized universally by humans, period. You either believe it or don't for your own reasons.
1. Most conceptual systems of the world are.God is a pillow for people who want to sleep through life.
2. Yes, for some people, but I would argue that those people haven't been reading very deeply in their sacred texts. The Bible, at least, is a very disturbing book to pretty much anyone. It shouldn't make you comfortable.
Regardless, your history with religion is very interesting (and seems to provide some good reasons not to believe) and it is definitely a question worth asking what the difference is, if there is any difference, between the personal religious ecstasy to which you inspired yourself (presumably), and "true religion" (if that exists). Also, you're a pk (preacher's kid). That explains everything. . I also "grew up in the church." My stepmom's a preacher, although not full-time or anything, and both my stepmom and my dad have worked at one of those "megachurches" since I was really really young, so I've been around pastors and the like since forever. Not really relevant to the discussion, but I figured I'd talk about it.
