If I am getting this guy right, the proof is in the probablity? I do not think that the probabilities is proof of God. Granted, if he was proposing that you cannot say God doesn't exist, because of these probabilities, then he's proven his case. And I'm glad he put forth the definations of what proof is, but I think he still just showed that the subjective thought of the probabilities of God's non-existence, is the proof of God's existence. If that is the case he did that, I do not think it worked.
the issue is that many argue informally, few argue formally to even appraise an argument we have to determine if its valid or not and validity is a concept derived from formal logic, a vaild argument is truth preserving.....In any formal argument it has to be vaild or sound ...
your question is more closely linked to the scientific argument an example of an argument field , there are off shoots such as normal science, revolutionary science , then there are paradigm disputes etc.... reasonlng with rules, clearly defined standards exist for what counts as evidence.....
this video is okay for a basic understanding of argumentation of what I saw it kept cutting out.. my area of study is philosphy ( relgious in particular) jand kudos to the thread starter...
it really helps to understand the methodology of argumentation and its a very profound area........
