You are confusing You-level and mankind-level, it was never about You. Meaning is there, but its not kind to people who think themselves as center of universe and mandatory part of it (we all are of our own version of reality but thats not what I mean).

Life well lived is a life thats easier to let go, believing in afterlife or not. Now what does that mean is highly individual but for most its around friends, family and children, mostly children. Most prople with kids have no problem seeing that meaning in mortality, plus there are even more logical and potent arguments (resources, selfishness, not ending up with immortal dictator forever etc but thats for longer)
