Totally not the same. Religious people believe the afterlife is better than real life and the OP was curious why they aren't speed running to get to it.
A blank nothingness is not an upgrade for most people.
Be scared of dying. The whole context of this thread is someone asking why theists are scared of dying, when the answer is the same reason that atheists are, dying can suck, no one is 100% certain about anything except for zealots, and fear of death fundamentally does not come from the logical part of our brain.
A blank nothingness might not technically be bad but there are plenty of ways that transitioning to that nothingness could be absolutely terrible. There are also many people living very enjoyable lives that want to keep the party going so to speak.
I for one am an atheist and madly in love with my wife. You bet your ass I'm gonna try and squeeze every last drop of goodness out of my life.
It's relatively worse. If you have nothing you won't be around to complain about it. But having a good life is totally better than simply not existing.
It's not relatively worse, it's just objectively neutral. It cannot be relatively worse because it is not perceived or felt to be compared. It is just objectively neutral.
It is not zero or null, those are both conditions you perceive, it is the complete lack of perception and being. You cannot have lost anything if you no longer exist to perceive any loss.
There is. Also, if you want to mourn or fear that loss, you have to do it beforehand. Thus making the reaction to fear death completely rational for atheists.
