When I say Know, I Mean based on the observations we can make we come to an assumption of outcomes.
Is not "assumption of outcomes" faith?
Assumption equals: a thing that is accepted as true or as certain to happen, without proof
Perhaps you meant "awareness of outcomes?"
So I can say I Know that if you heat glass to ~1500c, It will melt..
How do I know it works? millions of experiments and observations...
Hence awareness of own observations or information (experiments done by others that you've observed in some fashion, accepted as valid - or faith in their methods).
I Know that the temperature changes the molecular structure of the glass thus changing its density and stability.
I'd use "understand" here instead of knows.
Now, I Could say that the temperature changes the molecular level of the glass because thats how God made it...
That means, that I don't know why it works as it does but I do know it works and I can map some of the process...
Same goes for Nature and God for example..
How does that follow? Or why would you not know (be aware) of the why if attributing to God making it? If knowing it works and aware of mapping the process for own purposes, then the why I think follows. God/Nature provided understanding the how so you could have purpose in using it in your life/experience. Without that provision, it would be beyond your current natural existence.
