Did farmers spread or did farming spread?

I would say the answer is "farming spread." Farming did spread across the world peasants would plant crops and grow them to sell them to make profit and support their families. Farming is world wide and farmers can move to different places but they mainly stayed at their homes to grow their crops.

Hope this helps.
