No one is forcing you to believe anything.
But if it as you believe that everything proceeds from the material world and that evolutionary forces are responsible for the spirituality that has always existed in overwhelming numbers the it can only be because spirituality provides value and function advantage over materialism.
Otherwise you are literally arguing against science.
That’s rather nonsensical.
Everything about existence points to natural processes. Not a single event in all of human history has been shown to have a supernatural cause.
As to spirituality, what evidence do you have for "spirituality". You confuse "spirituality" with human personality. Many ancient peoples had beliefs in gods, spirits and all sorts of superstitions which were used to explain phenomena they didn’t understand. The only thing we have ("we" meaning those who don't embrace your particular theology) is your assertion about something you call "spirituality" but are unable to define in any meaningful way. It seems you're actually using terms you don't understand to press your fundamentalist religious agenda. Why don't you show us all the evidence that places something you call “spirituality” into a meaningful context?
