How much do you like philosophy?

Again, the set Craig is referencing is not "everything". The set is "everthing that begins/began to exist", which he says must have a cause for its existence if its existence had a beginning.

I do understand his argument, honestly. What I'm saying is you can't infer the properties of one thing from another, which is what he is trying to do.

P1 Everything that begins to exist has a cause.
P2 The universe begins to exist. It is therefore in the set of everything that begins to exist, but that it has a cause has not been tested, therefore P1 is not necesarrily true. It must be tested in order for P1 to hold, but once tested there is no need for the argument.
