What I'm taking away is that the inability to prove non-existence does not constitute proof of existence, but I haven't read the book.
I'd go a step further. If you said there's no Big Mac on the table then I can't really ask you where. Nowhere. Prove it? There's no further proof beyond it not being there. It doesn't exist to manifest proof of its non-existence. It simply isn't there, you'd tell me, since you ate it for lunch, and I may tell you that it is. At which point all we have left is skepticism about our individual ability to see Big Macs which may or may not be there. This makes asking for proof of non-existence a strong argument for me to demonstrate that you can't prove that I don't see a Big Mac, but this is not an argument which is going to make anyone see a Big Mac that they didn't see before so it's a poor argument to use if you want to change the other guy's mind.
Again, for the millionth time. No one can prove with concrete evidence that God does or does not exist. These are matters of faith.
These are matters of faith. These are matters of faith.
Faith is believing in something that you cannot, at present, prove. That may change in the future.
Conor McGregor said he will knock out Rafael inside of a minute in the first round. This a matter of faith. It's not a fact simply because it hasn't happened yet and you can't prove an event will happen until it, well, happens. The difference is that he will have a chance to prove his belief.
I think you are thinking to deeply about Bertrand Russell's comment regarding a teapot orbiting the sun between Mars and Jupitor. Although no one can prove with absolute certainty and concrete evidence we, or at least most of us considering the type of people on this board, can agree it's a highly unlikely. As an Agnostic, and his perspective regarding such things, he consider a God just as likely.
Get it? It was a joke with truth in it for him. It is highly unlikely that there is a teapot in space. He considered the existence of God just as likely. Both he admitted he couldn't prove but the likelihood of either is so preposterous that for all practical purposes he lived his life as an atheist.
