Matter and energy can be past-eternal

[Alex K]

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.

The statements the big bang is a singularity and the statement classic physics breaks down at the big bang are not mutually exclusive. That's your first problem. In fact, the reason why physics (as we know it) breaks down is because the big bang is a singularity.

In which sense precisely "is the big bang" a singularity?

Your second problem is ignoring where most contemporary scientific evidence points to: a cosmic beginning.

Again, it's one thing to say, "Yes, most evidence is pointing in this direction, but this argument for a past-eternal universe is very strong and here it is."

So tell me. What are your emotional reasons for ignoring science?

Don't be silly and stop simply restating that "scientific evidence points to a cosmic beginning" and be more concrete.
