And, you know, the fact is, if you believe in evolution, we all have a common ancestor, and we all have a common ancestry with the plant in the lobby. This is what evolution tells us. And, it's true. It's kind of unbelievable.
You know what, we don't know diddley squat about brains and no one has a clue how these things work, so don't believe what anyone tells you.
Your perception of the world is ... really a fabrication of your model of the world. You don't really see light or sound. You perceive it because your model says this is how the world is, and those patterns invoke the model. It's hard to believe, but it really is true.
