Wrong. If you look at some very isolated tribes in Africa, South America and Asia which lead very primative lives, many of these laws havn't been established.
There are exceptions and isolates for everything.
You're getting into very deep water there. I can tell you now that most historians would strongly disagree with you. It is universally accepted that religion has had a massive-and very important-impact on society and we wouldn't be where we are without it.
I'll use the same argument here I use when debating about extraterrestrial life: You're thinking awfully narrowly. We may not have an exact facsimile of modern culture and society had religion not ever been, but I firmly feel that there would be some form of society, though likely radically different from when we are used to.
Religion, much more often then not, is not the true cause of war. Often it's used as an excuse to cover things up, but scratch beneath the surface and there's a whole host of much stronger reasons as to why that conflict occured. For this reason I get very annoyed when people tell me that religion was the cause of my home country's war, when actually it had nothing to do with religion at all.
I'm aware of this argument, and I have used it on friends who cited the Inquisition and Crusades (among other things) as their reason for splitting with the Catholic Church. (I was raised Catholic and went to Catholic school for a long time, so I'll speak from my experiences.) I've always viewed those as bullshit arguments, as, in order to truly split with a religious organization, one must disagree with its principles and not merely its leadership and past acts.
That being said, though, the fact that religion is so often used as an excuse for varying types aggression is truly saddening. It also exposes some of the inherent problems in allowing large, organized, dogmatic religions gain power of any sort in a society. A country's ruler may just want tighter control over the people, but should he package it as a religious mission, odds are good he'll get plenty of religious nutters to go along with it. If religion were not used as justification for warfare and other forms of aggression, odds are good we'd have fewer people so willingly fighting for unjust causes. The specter of religion and one's supposed eternal soul can really weigh heavily on people's minds when making that kind of decision, and though the root cause of a conflict may not be religious, those actually fighting could potentially make it so.
