The Second Predicate Is True That the Universe Didn't Exist

I'm genuinely agnostic on the truth of the second premise whether the universe began to exist. And so I would like to grant for the sake of argument that the second premise is in fact true that the universe did begin to exist because I think that will corral us over to the first premise. So here's my principle. Whatever has an efficient cause of its existence has a material cause. If you have an eponymous premise, you can have a second premise that something like the universe has no material cause, conclusion, therefore, the universe hasNo efficient cause ofits existence.
