Well, you have fake nature and true nature.
To me, true nature is a word given by the evolutionists to the process of constant change. Nature however, is not always time related. Therefore nature is also a state of things. So to sum up the already brief, it's existance and change at the same time.
The fake idea of nature comes from people who think that nature was everything until humans started playing god. Why? You can't just say something without proving it, without proof, an idea will never be more than that. It's like when an evolutionist proves evolution exists, then a priest thinks he's a smartass when he says "well, God exists to me as long as you can't prove the opposite". Science doesn't work that way friends. When you say something, you need to back it up. Something isn't true until someone proves you wrong, but something becomes true when you prove it.
So what I'm trying to say that in my opinion you can't say humans act against nature when you can't prove they aren't part of it. I dare you to define nature and then explain why mankind and what it does isn't part of it anymore.
Well, I guess you can see that I've had this conversation before, and what some other people were thinking
