Religion is an eye wash. Man is destined to war because fight is in his nature.
1) When there are multiple religions, they fight to prove their religion right.
2) When there is one religion they form different groups/sects and fight.
3) When there is one sect, they find skin color/ethnicity as a reason to fight.
4) When there is one ethnicity they fight on economical grounds.
Fight is inevitable. So the books(Religious) have been written to give man a reason to fight.
Books smartly gives a reason and divides the man into two groups to make sure one half survives.
If he doesn’t do that, man will be fighting every other man for random reason like a royal rumble match and then everyone is dead.
I know this sounds funny but if you think about it, this is the ultimate truth.
Now a man may choose to write/explore another reason or his form of ‘TRUTH’ and maybe write a book. But either way, he’ll become a part of the same system.
