Eventually I came across this Q&A by William Lane Craig to attempt to answer what Sean Carroll called the Quantum Eternity Theorem.
Here's the first part that truly struck me:
"Saying that the time variable t runs from −∞ to +∞ just implies that quantum time evolution is information-preserving: “given the current quantum state, we can reliably reconstruct the past just as well as the future.” In other words, we can extrapolate from the present indefinitely into the past or future. This allows us to describe a moment prior to a given moment if there is such a moment; but in order to know whether there is such a moment we must look to empirical evidence. "
This was very similar to an argument I got elsewhere that things like quantum mechanics don't really address whether or not material things were created or not, but rather describe "already existing systems".
This is part and parcel of how apologists will try to evade the kinds of points I brought up saying how we have some evidence that "something material has always existed". It's effectively a way to insist that there is a metaphysical question that can't in fact be answered by any kind of scientific evidence.
In order to respond to this, it's very important to see exactly what the theist is claiming here. As charitably as I can interpret them, it goes like this:
The material world is described by laws (or regularities) that make it look like it has always been there, if we assume those laws have always applied. However, theism does not assume that those laws have always applied. Effectively there is no logical contradiction to believe that god created a universe that looks like it can't be created or destroyed once it exists.
So what are we to think of this?
