Imagine a future where...
Imagine a future where people stop believing in Gods and adapt to believing in universal principles instead like love and compassion and the future is all amazing and everyone loves and cares about each other, and then one day.. People start joking.. "Hey what if we're wrong, maybe that old mythical God from the bible was real!" And then all of a sudden.. The jealous God really does have a second coming and returns, and he's lonely as hell and pissed off and just starts murdering and eating everyone like in the show Attack on Titan.
And he's like.. "WHY DOESN'T ANYONE BELIEVE IN ME ANYMORE?! WHY?! WAHHH! WAH!!! he then starts crying and uncontrollably and starts grabbing humans and mercilessly eating them.
Did you have just taken something?
Believing in one God and living accdg to the universal principles is possible, that would be ideal.
