Well, the equations that predict black holes also predict white holes, and the big bang is functionally equivalent to a white hole. And we have found black holes. So…seems like the most plausible explanation for the big bang is…it was a white hole. Still can’t extrapolate backwards for the same reasons, but there are at least implicit causes of white holes suggesting there was spacetime before the big bang.
