Honestly examining the historical, philosophical and scientific arguments for and against the existence of a deity.
Common sense.
Lack of real proof.
I have yet to see or hear any evidence, only conjecture and confirmation bias proofs, for any God.
I think the question is....why wouldn't you? You believe what you're taught.... Until you're old enough to question that which you've been taught. Religion, seems pretty regional to me.
I'd rather ask: Why would anyone believe in the existence of a higher being?
If people find their faith comforting, then I can understand clinging to it. I don't understand religious dogma, especially within Christianity, since it appears to go against much of what such a "gentle" religion appears to stand for.
But, the Bible is full of contradictions, so I guess I should not be surprised.
All the pain and suffering and wrongfull convictions
Ernest Hemingway once said that every aspiring journalist needs "a shock-proof, sh1t detector". Mine works just fine and I can recognise bulldust when I see it.
I only believe in things that can be proved scientifically. There is no scientific proof of a Higher Force. If there is, I would like someone to let me know. I can understand the need to believe in a god. The belief that we are not alone. That you don't go into an eternal oblivion once you die. I would love to believe, but I just can't understand any of the justifications made.
I don't question God's existence ... I flat out deny it.
Why? Because of the lack of scientific evidence for any deity.
We live in a natural world with the default set to the "Natural". Any Claims to the Supernatural world require supportive evidence .
"Extraordinary claims require extraordinary evidence". - Carl Sagan
In this, the existence of any God/Gods isn't even of question . . . it should be "naturally" dismissed. The claim itself is illogical and unreasonable. This is why the burden of proof lies with the claimant and NOT those whom would dismiss such a claim.
It is important to note, that most Atheist, when given ample proof, would absolutely believe in any God/Gods or supernatural claims of the like.
Looking at the universe with it's orderliness and the marvlous way the human body is made who could ever deny our creator God.
God Himself requires that of every man.
You have to be either for or against Him---you can't just coast through life.
(Well, you can, but I wouldn't want to live a vegetative existence.)
god is a particle not a person.
You are the god you seek.
