Matter and energy can be past-eternal

Do they, though?

Yes, I read about them and talk to them.

Could you cut to the chase though? You seem to think most contemporary cosmologists do not think the universe is past-finite. If that's the case, then we should end the conversation because you obviously don't know what you're talking about.

It's one thing to say, "yes, most contemporary cosmologists are leaning towards a past-finite universe, but here is an argument for why they make be wrong."

Instead, you're misleading people by acting as though most contemporary scientific evidence is not pointing towards a past-finite universe.

I haven't made a survey but I would assume that most cosmologists would agree that any past singularities one encounters in cosmological models are merely points where classical relativity breaks down, and no one knows what theory correctly describes the universe around that point, and that consequently one cannot state with any certainty that time simply ends there.
