I know plenty of non-religious people I couldnt count one nihilist amongst them.
Religion requires all kinds of additional burdens over and above setting some standardized life milestones, the cost is very high (submitting your mind to external control) for minimal return (knowing you met someone elses goals).
I don't mean to sound confrontational, but religion is (in my view) very damaging; it prevents people from asking questions about what is right, by prescribing what is right.
