In English, it seems there's a lot of figurative speech about the tree. Why is that?

In mythologies, legends, and novels, trees represent "growth" and "life." Trees are easily referenced for symbolism and meaning. It also centers on a lot of religions like Christianity, where one of the first bible stories is about the tree in the garden of Eden. I don't think there's one specific reason as to why trees are used a lot figuratively, but rather that trees are a part of nature, and thus part of the human experience. So inspiration is taken by nature and living things that humans live in and around!
