Lazy Atheism?

If it is about land use, then there would be farmers fighting farmers, shephards, fighting shephards.

I disagree. Famers fighting farmers leads to fallow fields, and herdsmen moving in. Shepherds fighting shepherds leads to flocks being whittled down by straying and predation.

However, unless you're raising goats, there's only so much decent pastureland, and it comes as no surprise that this land is arable and both herders and the farming communities that were feeding the first protocities wanted to turn that land into wealth.

Of course there will be some internecine warfare, but not as a general thing, imo.
