I find it convincing too. Check out the &#x27;Big History&#x27; lecture series. Particularly the lecture on the transition to agriculture. I was inclined to think that humans transitioned to agriculture as soon as it was &#x27;invented&#x27;. But the lecture suggests that humans knew perfectly well how to farm long before, but didn&#x27;t because it seemed like too much hard work. We didn&#x27;t transition until forced to by climatic conditions.
