As described in Part 1, God cannot be proven. Thus, we have to decide on a “belief”. This is something we accept as being true which cannot be proven to be true, but also cannot be proven to be false. And by “prove”, I mean by way of a valid proof, either using the Scientific method, or valid logical arguments against provable assumptions. Anything less is not real proof, no matter how good it sounds.
Very often, a person who holds to a particular belief will go to any length to “force” that belief on other people. Often, this can lead to violence. This is very sad and actually pretty silly, since for a belief to be “real” to a person, they must come to that belief on their own. They can be guided, but not forced. If you cannot prove something, then you have no business trying to force someone else to believe it. For that matter, even if you COULD prove it, you still have no business FORCING it on someone else. If a person wants to believe that the world is flat and has no interest in finding out they are wrong, then that is THEIR problem, not yours.
Any way, there are two main beliefs about God. One is that God or Gods exist; a person who believes this would be a “theist”. The opposing belief is that no God exists; a believer of this would be an “atheist”. Absent proof, either belief system is equally valid, by definition. And if you have heard of a “proof” that God does or does not exist, I can practically guarantee that “proof” was not valid, since all proofs available to us are rooted in the Natural, and God is not.
Note that a person does not have to be either a theist or atheist. Either one requires belief and it is quite possible and even likely that people start out without either belief. A person who has not reached either a belief in God or a belief in no God, is referred to as an “agnostic”. Such a person does not “know” if God does or does not exist; the wise ones attempt to find out because if He DOES exist, a person’s relationship with him might be beneficial or detrimental to them.
In part 3 we will consider some of the beliefs of theists. There is nothing further to be investigated about atheists; once it is believed that God does not exist, there is no further path to follow.
