Adopting Religion for fear of what may transpire post death?

[Ace Otana]

Basically what he mentioned was that he was playing it safe, and that is what majority of the religious people do (according to him). If he was wrong, no problem! It did not cost him a dime to believe in god, so if god did not exist, after his death, he is simply gone from the face of the earth and his body rotted away in his grave.

Well he's wrong. What if he believed in the wrong god? Perhaps insulting any real god and ending up in hell for it? Perhaps Islam was the correct religion, perhaps Norse, ect. We could all end up in hell, just as we could all end up in heaven, but more likely we'll all end up back as we were before we existed.
What he like pretty much every theist is like, they won't ever except the possibility of being wrong and ending up in hell. They all believe that their immune to hell, they all believe they're going to heaven no matter how they've lived their lives.
The truth is, they are living in a fantasy world of their making. Because no one would invent a fantasy where they are faced with a most undesirable outcome.
To see a fantasy and recognise it is easy, to accept it, is a whole other matter and often too difficult to handle.

For all we know, we atheists end up in heaven for using our reason and judging things based on available evidence, and theists end up in hell for scaring and killing people for personal beliefs.
