-Atheistic churches (social, life events, service)

These already exist. I think Unitarian Universalist churches are the most common ones, but at least where I live we also have Sunday Assembly.

I grew up in one and this describes it fairly well. None of my family believes in god but appreciated the community. There is an orientation towards general spirituality, however any individual defines it for themselves but the purpose is more for general community and moral thinking, etc.
