> Nihilism then?”. The Bible unabashedly says “yes, if you don’t have God”
I am not trying to argue theology here, just giving another perspective.
I was raised an an observant Catholic household, and I went every week from ages 5-19 and missed only a few times due to illness. But I never believed, I just don't have a spiritual bone in my body. None of what you quoted from Solomon about the impermanence of our material acquisitions sounds profound -- it seems obvious.
But the main reason I'm commenting is this idea that non-believers must be nihilists [1]. I want to assure you that I find meaning and purpose in life, but it isn't dictated by some holy person. Pain and suffering and happiness are real and even though we are all reduced back to molecules when we die, what we do and how we act during out lives matters to the people (and wider world) around us during out lives and for a while after we die. I get the same impression from other non-believers. It is a colossal failure of imagination to think that without God people must believe nothing matters.
[1] This footnote is to acknowledge that different people have their own interpretations of what "nihilism" means, and so any statement I make about nihilism will result in some group of people saying "you don't even know what it means!"
