Please focus on your 100% claim. I am not the subject of conversation.
My thought was not that you are the subject of my conversation, but what you mean by 'knowing'. Scientific knowledge is a body of past theories about how the world works that have been verified to apply without exception experimentally. In short, a scientific leap of faith is what a logical mind does with past evidence of success. The benefits of scientific reasoning have brought profound changes in our understanding of the universe that any not indoctrinated person can see. Science does not require, in the sense of demanding, faith; it earns it via tangible evidence.
So when I say that the probabilities that molecules self organized etc. is too remote to have happened, you must establish scientifically that some other agency did it which itself must have had some agency to have caused it creating the It's turtles all the way down argument or a non verifiable notion that the creating agency had no creator itself. That then violated Occam's Razor. Having eliminated the unprovable, a scientific mind, while it may not know how something happened, seeing that it did happen, theorized how that could be leaving the knowledge of 100% certainty there is a natural explanation, and since molecules are self ordered, they did that somehow without outside mysterious creator type intervention. This is just the nature of logic built into the human brain.
Now personally, between you and me, I know that God exists, that God, human consciousness, the universe are all the same thing, so not that He stands somehow out of it. Awareness of the unity of all things is a conscious state, the most profound one I believe, the human mind can experience. It is a peak experience, that confers the sense of ultimate joy, love, and good. It's not about a mysterious being other than He is the being we all are and do not realize is there. God is when we, the ego self, is not and we, the eye, is an illusion but one of deep persistence and conviction. I think you can't have both God and your ego self so I would call belief in the man on a cloud a fairy tail of self flattery.
