Religion
is there a god, if there is, it'll be a god that regrets inherently that he made himself known to us.
if there is no god, some of us will realise that life is easier;
"imagine a world without heaven"
education helps us all, if god is there, he'll agree that we learn philosophy and science.
if civilisation has progressed, then what we have now is an improvement to what is in the past.
however progress will never saturate the entire human race.
for those beings that are advanced mentally they learn philosphy; those lagging simply believe in religion.
if there is a heaven we will be baffled see not only mother theresa and buddha, but also its crowded with everyone--because there's onlyy one heaven, but each religion believe in a different one. assuming all is correct, then a composed (of all religion) heaven will have good people, great leaders, and murderers and rapists that repent their sin before they die, we might see the entire aztec clan there that practise canable-ism. Towards the centre arena we could well glimpse entire nations of celtic heroes fighting and feasting. buddha will be there to remind you that reincarnation department is 2 miles due south.
