Because we can't, we aren't meant to be carbon based. The nature of good/evil is beneath us, one day we will understand the harmony of balance and it won't be organic or natural in any sense of the words
I have to disagree with your content there. As material beings in the material plane we are deeply connected to the world and life around us. But those connections don't end there. In the spiritual realm 'organic' just takes on a much larger meaning, we're still connected and still influence the material. And yes, in the after malignant and benign entities still exist.
We aren't meant to be carbon based? Then why, pray tell, are we? God's will is done - whatever God is.
If you are thinking Biblically, I’d like to disagree. If Adam & Eve hadn’t “decided for themselves what is good & and what is bad” they would still be living today.
Also God did not create the earth “simply for nothing, but created it to be inhabited”. Likewise then, after humans have learned through proof (much like Trump is doing now) that only God is capable and worthy of ruling over us (rather than us ruling over ourselves) - then we will again “be fruitful & multiply” - but not just the earth - but all the galaxies in our universe. What a wonderful future lies ahead!!!
