Mathematics and the Universe

[DD_8630]

In QM also every observed event has a precursor which causes it.

That's not entirely true: quantum tunnelling (inc. radioactive decay), vacuum energy, etc, do not have precursor events. They are truly spontaneous.

Also The different interpretations of quantum mechanics imo show that it is (still?) impossible to draw conclusions on discreteness, identity and causality.

But it's these uncertainties which refute discreteness (et al) in the first place :p

Since we seem to be approaching consesus of sorts, do the non-deterministic type mathematics of quantum mechanics suggest a chaotically spontaneous existence of the universe?

Short answer: no.
Long answer: let me lecture to you for a few years :p

If not, then why should the deterministic type mathematics of classical physics and general and special relativity suggest divine creation?

Why indeed. Surely it's better to ask the proponents?

But, if so, then doesn't that put the lie to "divine creation" being reflected the mathematical description of the universe?

Exactly.

Though both alternatives are false: deterministic mathematics does not represent the mechanics of reality (insofar as we can tell), and mathematics in general does not point to a 'divine creation'.

I think you need to sort out your dichotomy :p
