“I am afraid we are not rid of God because we still have faith in grammar.”
(Nietzsche, Twilight of the Idols, “‘Reason’ in Philosophy”, section 5 end.)
The efilist and the lifeist are both completely deluded and thereby immune to knowing the fact of death (though not to that fact itself, of course). Thus the Neumann quote I added could’t help them. Perhaps it was too summary? 
Here’s from the prequel to that answer of his:
Objection: Is it not contradictory to say that nihilism is both true and yet nothing more than an arbitrary impression, a mere prejudice?
Answer: Yes.
Objection: Does not this prove it false?
Answer: No. Any faith in anything’s being something rather than nothing, any desire to live rather than die, is self-contradictory. The self that it contradicts—anything’s true self!—is reality’s nothingness. Life in all its manifestations is, and must be, self-contradictory. Refusal to acknowledge its self-contradictory character is at the heart of all mankind’s self-delusions or prejudices, especially of all moral-political passions (“values”). Bigotry is unavoidable for men (or beasts) determined to be something rather than nothing!
