Are you saying atheists don't have a natural need for something to help them get through life, to make life meaningful...?
No. It's just that atheists are a catgory of people who do not recognize religion, religious behavior, or the peer pressure to adopt religious norms as meaningful to them. My own story was that I was like any other kid wanting to have fun, making things, etc. but where it came to going to church I asked questions while none of my peers did. I was 8-9-10 and asking questions why we went to church, what is God, who is Jesus, etc. I was given answrs that did not add up. I kept asking more qustions, and never got any that made sense to me. I simply was not attracted to the groupthink. My Catholic and Baptist cousins were totally absorbed in their religious experiences.
Cognitve psychology has proposed the biological phenomenon of "wired for God", that the vast majority of humans evolved to believe in a social norms even if they are not fatcual or rational. The brains of early humans evolved before language and rules of thought existed. It is estimated about 85% of all humans are "wired for God" which would imply that I am one of the 15%.
That said I have led a life of various pursuits, as a competitive cyclist since 1983. This will be my 40th year. I've been in bands, and starting a new project. I've had numerous businesses over the decades. So I am not empty of meaning, I just did not feel religion as a viable path for meaning.
From what I observe many theists are attracted to religions and religious groups for various reasons. I've watched my sister go from religion to religion seeking truth and inevitably being dissatisfied. To my mind I asked why she sought truth from what others believe, and not from her own path. She always had this notion that others knew something she didn't. I pointed out that religions rely heavily on assumptions, not fact. She could always find a "truth" but upon examination it was always going to be dubious given the assumptions. From what I observed she was looking more for a tribe than truth, and I suspect this motivates many believers. This certainly is supported by the biological mechanisms in early humans that relied on the security of a trusting tribe to survive.
For early humans it was actual survival. Today I think that had become a survival of the ego. The fear that revolves around ego, and how public embarrassment and shame is something many fear, we humans go to many lengths to protect it. Studies show that people are more afraid to speak in public than death. That is amazing. We humans really desire approval by others, and having a tribe assures some degree of safety.
The atheist anti-religious scientist Steven Weinberg said something different:
Although he never tried to hide his atheism—perhaps only Richard Dawkins and Sam Harris have been more vocal—Weinberg was sympathetic to those who yearn for a more intimate conception of God. “I think a world governed by a creator who is concerned with human beings is in many ways much more attractive than the impersonal world governed by laws of nature that have to be stated mathematically; laws that have nothing in them that indicates any special connection with human life,” he told me. To embrace science is to face the hardships of life—and death—without such comfort. “We’re going to die, and our loved ones are going to die, and it would be very nice to believe that that was not the end and that we would live beyond the grave and meet those we love again,” he said. “Living without God is not that easy. And I feel the appeal of religion in that sense.”
Atheists don't say: we don't need any meaning. They say you have to find your own.
Look at what he says here:
those who yearn for a more intimate conception of God. “I think a world governed by a creator who is concerned with human beings is in many ways much more attractive than the impersonal world governed by laws of nature that have to be stated mathematically; laws that have nothing in them that indicates any special connection with human life,”
This is true from my observations. So many have anxiety about being ordinary, having to create meaning for themselves and build self-worth. This is burdonsome, and it is vastly easier to adopt a framework that comes with a notion that "You are special" to a God. But if a God exists is it really concerned for us? Look at defects. Look at people born with mental illness or disorders. Look at children born with genes that cause cancers, and they have to suffer through treatments they don't understand and often die. If you were God would you allow that? Is that how you would show concern for a child, giving it cancer? If not, then you can understand why the religious idea is so manipulative to our natural fears and anxieties, but even cruel.
It feels good to believe in a God so long as life's trauma and problems are not too severe, and we can solve them ourselves. Get cancer, prayer won't fix it. Arguably if you get cancer it was God's will, according to how many believers think. To get treatment might go against God's will, afterall God gave you cancer for a reason, yes? Can you see the trap of religious belief when life gets truly difficult?
