One can not proove why the bible isn't true without throwing in there own religious beliefs. Since I have no sturdy beliefs, I can not disproove it, but I can question it in ways I can only make sense within myself. I cant ask it in common language... I dont know how to word it to make sense... anyway. One can only truely say another religion is wrong because their religion is right. As you basically said, and in that would disproove every religion.
The one major problem with that is to have faith in god would to be without doubt. and I have great doubt in everything I believe in, without doubt you can't better your believes and self. If you doubt one thing about yourself you give yourself a wide spectrum of choices to edit upon. If you corner yourself into one thing, close minded onto that one thing you will never be able to fully understand anthing else. Now this next part may not apply to you, but it does to most people who settle on one thing, I will use Matt as an example. He is the exact opposite of you, or a christian I suppose. He has set his mind on it that when we die we die. He is close minded on it and beleives nothing else. Therefor when he looks upon anything that isnt that he has a biased one way view of looking at it. When he sees christianity he thinks god and heaven. Heaven contradicts his beliefs therefore he cannot see past those two parts. He can't see the good teachings of jesus. He can't see the moralities of the religion.
Another example now... hmm... say there is a christian, and he thinks of wiccan. Pagan even... When he hears this he automatically thinks of goddess and gods... more than one, many. This being known they automatically disproove the whole thing. They cant see past that part since it contradicts with their own beliefs.
If one person has doubt in there mind they can see past many things that would keep others in a square view on life. Than agian with doubt you also cant commit to one thing. So therefore agnosticism is what I follow... I just couldn't be Christian, my mind wouldnt let me..
If one meditates and concentrates long enough, and has enough will, they can break there own mental boundaries, and see and understand what the average human cannot. I have not myself done this, but I have scratched the surface of it. Seeing fate. I have seen that fate of mie and the fate of few others. It is hard to explain, but every human being is capabel of doing so. They just have to connect with their primal instincts, their subconscious, and their weaker side of heir brain.
I'm finding the answers within our species. What makes are species do what it does, and how it does it. Our mind is much stronger than most beleive. A saying goes "If you think you will fail, you will; if you think you will succeed, you will"... This saying has more meaning than most think. One person can literally create their own reality. They can make their own pressence, and they can control how others feel towards them by how they do what they do. Even if what you were to say was true there are humans that are destined not to follow the norm. I believe I am one of those... And by norm I mean the crowd, the crowd changes. Currently the crowd is religion, though others may say its politcal parties, or school cliches, it isn't. Ultimately it is religion. Religion is the only thing currrently in this time period that one would die for. Many christians would die saying they love god than lie and say they dont love god and live... And if my theory is right I am destined not to believe in one mainstream religion. I am not destined to be lead by a rope, I am destined to explore and find my own answers. And only with true knowledge of everything around you can you find answers to yourself. A German philosopher, whose name is a blank for some reason, once said " you can not discover yourself until you discovered the world around you."
I am discoverinig the world around me. And if I let a religion drag me along. Making me believe a stronger force did these things for me, that I'm just a puppet, I would fail myself. I just can't think at that level.
