Farming can provide more food per square mile, and thus a higher population density, than the hunter-gatherer lifestyle.
Hunter gatherers required lots of land, and this limited the size of the tribe to what could be supported by the food within a reasonable walking distance from the camp. Camps also had to move frequently as hunting depleted the game in the area.
A farming community could sustain a much larger tribe size in a given area, and thus could muster a much larger number of fighters to go after any hunter/gatherer tribe which tried to encroach on their territory.

Good points BUT humans are built for the Hunter Gather lifestyle. Can move 20+ miles a day if needed, only humans and some Equines can do that. Once you get Dogs and Horses you get to the Mongol Empire.
Which is why the immigrant farming populations of North and South America, Siberia, Southern Africa, and Australia rapidly overwhelmed the natives engaged in hunting and gathering and primitive farming and herding.
