@Angelgz2,
err..I never said or assumed faith was bad. In fact I don't feel that way at all. I'm just trying to determine when something is faith and isn't faith based. I was being a bit facetious when I said 'science sucks' - again I was just trying to make the point that we have to differentiate between what is faith based and what isn't.
It would be more correct to say that I think the application of faith is incorrect to certain things, but I don't think faith itself is necessarily good or bad. Its valuation is a whole nother discussion!
btw, you have another possibility - maybe we are all part of a computer program made by humans in what we would consider our future from our current vantage point. So those future humans wouldn't meet the traditional definition of a God, but they would obviously have to have technological superiority to us to make us all feel like we were real etc..just an interesting aside..
So, to answer your question, why not believe in God. Well, two things. First, I don't know what that exactly is. The term 'God' has a lot of baggage with it. So, a creator? OK, so if a creator, I can hold that its possible, but I cannot just 'believe' it. Why? Because I don't know it. And what I don't know, I cannot just believe. Which I think is why we invented the word: possibility.
Which rolls to the second point. I don't think its psychologically possible to be genuine in a belief of something when your reason holds that it might not be true. In this sense of what I'm talking about, you don't have control of your reason just like you don't have control of what colours you see.
Now, I'm getting off the path here for a minute, but I think its important in explaining why people cannot 'just believe' - genuinely (important qualification there). In order for your reason to change, new evidence has to be given - new input that qualifies what you originally thought.
The way I see it, in this sense of the usage of reason, if you have doubts about the existence of God, you cannot reasonably, rationally believe (in the sense that I am using reason/rational). If you believe at this point, its more emotionally based, perhaps you would say more faith based.
I'm actually not sure of this last point. Its very difficult to get objective evidence to show that its correct. I could be wrong about it.
But more to the point, for myself, I never even get there. If my brain tells me hey this could be true or it might not be true based on an honest appraisal of the things I (think) I know (that 'rational/reasonable evaluation), then personally, I cannot just swing the pendulum to one side or the other. And I can echo your sentiment but turn it around a bit: What does it matter if I do believe? I'm not quite sure what I'm believing in in the first place and in the second place, even if it were to achieve a more coherent shape, who cares?
Its like believing without any hard evidence that Julius Cesar didn't like cabbage. I could believe it, but then I know in my mind that I don't
really know do I? So, that's what I mean when I say that my reason has to honest and genuine - if I 'choose' to believe that JC doesn't like cabbage, I would really know that I really don't know. And here I do believe that in these types of positions, people say they believe and hide the truth from themselves that they don't really hold that conviction (for many reason - social approbation, perks for belief etc,) Anyway, to top it all off, what good would a belief do for me that he hates cabbage?
I think that's where your faith comes in. But like Dennis Miller once said (paraphrased), I'm not the type to have a evangelical experience with the archangel Michael in my bathroom mirror..
