I am sure we all have more than one reason, but what is the main one for you?
Truths don't obey borders, religion does. If Einstein could, almost by himself, think up accurate laws for the universe. How come humanity as a collective can't do the same with any god/deity? It doesn't hurt my father was raised atheist and my mom was agnostic (but is now born again Christian)
That's hard to say, it was so long ago that I quit seeing truth or value in religion. I know part of it was Christian/Catholic religion's views at the time on gays, feminism, abortion as well as euthanasia and the glorification of suffering for the sake of eternal reward or improvement of one's character. In the face of those things, it just didn't hold up the way it used to for me. This was in the early 80s. Maybe seeing the rise of the religious right and the Moral Majority along with TV preachers added to my distrust and cynicism.
I also saw too much phoniness and hypocrisy at the personal/individual level among believers, but that was just young idealism and being naive because when I got older and started attending Unitarian churches I saw just as much of that. Now I know that's just how many or most humans are, believers or not.
When In church I noticed they were promoting things that did not agree with reality as truth. I figured the entire religion thing was BS. That and the fact that there is no testable evidence to confirm any supernatural assertion such as there is a god.
I have read lots of storys but the bible is not my fav as it makes little sence in the real world .?x
If I had any religion it would be nature. I go out into nature every chance I get. It is unbeatable when compared to ANY organized religion I've ever seen. John Muir said; "Of all the paths you take in life, make sure a few of them are dirt." He was right ... at least in my humble opinion.
I don't like organized religion because it professes "my God is better than your god."
Well, to start with, I AM religious: I'm an atheist Pagan. But I don't believe in gods or the supernatural. Religion isn't just about what you believe--it's about your values, and what you DO.
I do not follow any of the mainstream religions because their values suck and they are demonstrably wrong about the nature of the Universe. Their gods are imaginary.
That's why.
Science is my biggest reason. No one has proven there is one or many gods.
Ironically, it was on a retreat in a convent in Stepney, London, at the end of my 'religious years' that I came to the conclusion - over several hours at night and with an open bible before me, and after much soul searching (no pun intended) - that I simply DID NOT BELIEVE IT.
I studied a couple of other religions before it dawned on me that it wasn't just ONE religion I didn't believe in.
Because I've yet to find any religion that fits my way of thinking. I've always been a sucker for logic, and most all organized religions are anything but logical.
Plus I'm secure enough in myself, to not need the "groupism" that comes along with the "ole Sunday (or Saturday) meetin' houses".
I take bits of wisdom from many sources - along with life experience, and gather them all together, and pick out useful ones every now and then.
Religion is apart of my family for all the wrong reasons. I grew up Baptist and anytime I had a question about significant subjects I would be told not to question god. I was always told you're looking too deep into this. Just believe. That's when I knew I no longer had a rational belief in a god nor the rest of my family for that matter.
The contradictions in belief. "God is all knowing, loving, and eternal." Yet "God" gets pissed off when humans "don't behave" in the examples of the Great Flood and Sodom and Gomorrah. So, God/god is not above human emotions. The christian god doesn't sound any better than the Greek gods.
