There's more to religion than the conflicts it created. It is by nature the blind belief in something entirely made up for no reason whatsoever.
The difference between a moderate and a fanatic is merely of degree in that regard.
Sure it is true that it's a seductive idea to think that "something" is out there, but all that means at the end of the day is that humans are predisposed to feel that way, which isn't any support to the theory of it being real.
As for science only being theory, technology is the proof that it works. Now of course, the non-existence of God cannot be proven since there are always gaps for him to fill but it cannot be denied that the claims of nearly all religions have been thoroughly disproved.
However God(s) not being defined at all, or (quite often) simply surviving the disproving of its definition at a given time, it is probable that even if e knew everything that there ever is to know in our universe and beyond, God(s) could still not be proven to exist or not.
I agree with just about everything you have said, though no-one truly knows what is and what isn't. Sure science has proof that it works, but in the sense of religion and our reason for being here, it's all speculation. It's easy to believe science because it makes sense, but that doesn't necessarily mean it's true.
I am very science orientated, but I like to keep an open mind.
My point was that religion is good because it give people something to fight for, to believe in, a reason for being. To me, that is enough. If you feel whole because of your beliefs, that it allows you to feel like you have really lived and you are happy with your life then that is all that matters. So to me the only real negative is conflict with others. I think everyone is entitled to their own beliefs and should never force them upon others. Of course if one persons beliefs lead them to do dangerous acts then of course people are going to fight back but people shouldn't fight because they don't like that another person believes in a different god etc.
You can't say that it was made up for no reason. I mean you can believe it if you like but through reason itself it makes sense. Like I have mentioned before, the idea of God and following religion gives someone purpose and hope. Gives people happiness. That is a good enough reason.
Personally I believe God doesn't need to be proven. Of course I'll never truly believe until I have my own proof but I am happy enough knowing what I know. So long as I have the freedom to live my life the way I want to then that's all that matters to me, I will embrace the thought of God and live by the rules of science.
