why?

I was just thinking of this problem that we seem to not be able to avoid lately
Religion
For thosands of years humans have looked to a superpower
Power way beyond our understanding to explain what humans cant explain
like rain
so well lets have the rain god
how about the sun
we can have one for that as well
Harvest
deseases
strength
um what else
well what happens when we die?
lets mh.....how about we wrap you up,kill your wife,gather all your belongings, make some servants to stay in the grave with you and oh..dont forget the food for when you come back to life. Then put all that in your tomb with you..
yup thanks ancient Egyptians now we get to dig all that and put in the mesiums for all to see
Then people thought well.. if one can farm and raise a family and trade then one god is probably capable of doing all that...
One God to all
Today most religion insist of one God
My problem comes
If God ,one God ..is so powerfull
He panishes the evil
and reward the good ones
Then why we have to fight for him?
Why do we fill its just to take ones life and say ..you know he said some shit about my God so he or she has to die?
Why do we fill the need to attack a place,blow everything into peaces and take as many lives as possible in the name of god
I seriuosly doubt God has anything to do with it.
If he did how come Bin Laden didn't blow himself up instead he went into hiding scared of meeting his god?
How come none of these so called leaders of jihads never blow themselves up but send twelve year old kids to do it?
If thats god will, then what isnt?
