“Strictly speaking nothing should exist, because matter does not create itself.”
What sort of experiment could you run to establish this as a strict fact?
“Something outside the laws of nature must have been operating in order for matter to come into existence.”
You know we write the ‘laws’ of nature, right?
So, in a condition like, ‘nothing exists,’ we have no observations of that state. So we haven’t written any laws about it. Thus, whatever happens could easily be the natural actions that happen in such such conditions.
"So if you accept that you exist,”
Depends on what you’re using as ‘exist,’ actually.
“you should also accept that something exists outside the laws of nature,”
I don’t think you really know what the Laws of Naature are.
“and possibly, therefore, that those laws can be interrupted, as in the case of miracles.”
Well, miracles have to be outside the laws, or they’re not miracles, just low, low, low probability.
but, you know, demonstrate a miracle please.
