You BELIEVE God doesn't exist. Your belief isn't fact. No one can prove that God does, or doesn't exist. If you are wrong, you may very well wish you had the benefit of that belief. To not at least consider a possibility isn't the mark of maturity.
I honestly think people put more emphasis on "possibility of god existing; belief rather than knowledge" because it's religious in nature. Yet, if I opened an empty palm and tell you I have a penny, you wouldn't second guess nor say "I believe there is no penny but have no proof." You wouldn't be agnostic; you (I assume) would most likely be an atheist and boldly claim there is no penny there.
God is no exception to this rule that something that does not exist doesn't automatically exist all because it's religious in nature. The laws of physics don't change and spirituality is not "independent" from ourselves.
Everything we experiences is from our minds-our perceptions in thought, interpretation, and what we believe is real and not real.
In the case of god, there is a lot of evidence, if one likes, that god does not exist. More so than the other way around. It isn't dependent on personal experience but basic psychology, physiology, and environmental influences. It's not something "beyond" or "majestic" no matter how much importance and need for worship we try to make of god, it doesn't exist outside the human perception and
belief about it.
I
know god does not exist. I no longer need to believe this. My experiences, logic, and plain common sense has shown me that an entity does not exist independent of the human body.
If I used the term "god", god (the concept not any religious view) would be life. It is
energy and nothing more. Everything is made up of energy. Our thoughts are also energy (nerve impulses) as well as what we call "feelings from our heart." What we call spiritual is just a way of poetically describing the combination of senses we can't describe in language. Nothing wrong with that. We conclude, some of us, these senses are the result of god(s).
It is not so. That is what I
know. Another factor is if I took out the Vedas, the physical nature and attributes of life, the sacred text like the bible, and quran even, the stupas, and offerings and asked you to describe god without referring to
any physical thing nor
any human concept how can you describe it?
John, Paul, and Peter are people just as you. I'd say the same thing to them and Jesus as I do to you; so, their words don't count anymore than Muhammad's and Baha'ullah. Each have their strong points. I rather read the sutras and Upanishads than the Bible and Quran any day.
Personal experience and knowledge (two and two together) shows me spirituality is part of our mind and body way to make sense of the world. Whether we want to revere it or worship it or not is up to the individual's personal preference. However, it's all
belief.
There is a post that explains my point well:
Is superstition a widely held justified belief (Post 6)
There is nothing wrong with the
belief that god exists. Not all atheists put down people who believe in god and the belief itself.
You just got to accept that many people actually
know there are no gods and there is no exception to this rule. It's hard for me to make a god/entity just pop from thin air while it may be hard for you to make god disappear.
That is something we got to accept.
