Well, think, when your brain is dying, you are sinking straigt into the world of those same imaginary phantasms, they then make you experience them as the superior reality. And your expectation of your final death is futile because the biological "clock" of your brain is stopping too.
Let's be honest. The Atheist worldview is plagued by doubts and futile ambitions and has the great God-shaped hole at the very base of science, namely the Quantum Choice problem. The Theistic worldview is perfectly consistent and in full accordance with all the facts, particularly with personal religious life. The difference between religions works as the trap for human passions.
