No, we can theorize on why we have gravity and what might possibly be causing it. These theories aren't just dreamed up, they have some basis...a lot of basis. You can't really compare that to the idea of a superior being. We may not be able to say for certain what is causing gravity but we can quantify it, which is a whole lot more than what I can say for religion.
At the root of it, religion holds to this idea that humans are somehow perfect and I think that leads to the false belief that we are somehow superior.
Religion is actually quite quantifiable, however would require many hours of close study regarding its history. I think that you meant to say "which is a whole lot more than what I can say for
God". Those are two distinctly seperate things. Many have alluded to the difference between religion and spirituality with God.
Bogey_spotter ... It sounds like you're a bit of a deist, many of the founding fathers might not disagree, however they might throw something at you anyway.
WannaGo... you're argument is interesting, however a Christian is going to no doubt argue that there is still "evidence" of God's actions, thereby destroying your Galileo argument. Granted thats not something they can prove... just making sure you are "aware" of this counterargument.
It is my personal belief that God can inspire you to do the right thing, and can show you the path. IMO you must be proactive and seek him out, pray, and watch for the signs. I DO NOT believe that he will do anything for you are magically solve your problems. I'm not going to say that its impossible however.
Outside of that, interesting read everyone! Happy New Year!
