Re: “Then where does the matter which apparently spontaneously comes into existence come from?”
From energy. The universe has a low but non-trivial background temperature due to energy. Make the universe's volume very small and it gets an enormously high temperature.

High temperatures and pressures cause energy to transform into matter - as occurs in linear accelerators but more so since our best linear accelerators produce negligible energies compared to what once, briefly was the norm throughout our universe. E=MC^2 also means that M=E/(C^2). Exceedingly high energy and pressure forms matter.

If all the matter 'evaporates' . . .
Then where does the matter which apparently spontaneously comes into existence come from?

How about this. The Universe is infinite. Meaning there will be an infinite number of 'Big Bangs' and 'Big Crunches'. Each of the 'Big Crunches' will collect matter from 'neighboring' Big Bangs till it has enough to 'Big Bang' itself. Which in turn feeds the fodder to fuel the next big crunch(es).

With hundreds of Billions of years between the Bangs.
