If you can read this, you are as lucky as I am.
I have already explained it. But I will explain it one more time. Science cannot explain how something came from nothing for that would clearly entail a supernatural event, namely, creation ex nihilo (creation out of nothing). If you don't agree with that assessment, then we will have to agree to disagree.
I don 't want to speak for the other gentleman, but I think he understands the conclusion of your argument.
Part of that conclusion is to suggest that there is the possibility of a metaphysical answer, the assumption that scientific inquiry will never figure it out, and the claim that there are causes that somehow affect physics, but then they somehow don't, which I don't feel has been discussed or explained to any real degree outside of a link and a quote.
