>>40554966He's right. I can't remember for certain but it's in a very similar vein to the knowledge that the watchers taught (they didn't just teach them sorcery, they taught them things makeup, astronomy, time, weather, etc.) Gardening is about control. Control of what gets planted and harvested, control of the environment it's planted in, control over even the (plant)life itself. Not only that, it also involves driving off and preventing pests.
Hence why it's demonic. Like everything, it takes control away from God and puts it into your hands. If Adam and Eve were gardeners taught to tend to Eden, they'd have driven the snake out for being a pest. But then of course there'd be no story. So God kept them ignorant. Though not as ignorant as the original post.
