Another way to look at religion

Religions were born out of fear rather than love. Fear of death, more exactly. Apparently, that is the most powerful fear of all, closely followed by the one of being / remaining alone.

Makes sense when thinking that religions (Christian religion, especially) prepare you all your life to face the afterworld, whichever that might be. This is at its core, to be precise, since nowadays a lot of it turned into a genuine 'business'.
