There are a lot of 'Maybe's' there, redewnur. First, some thoughts on your thoughts on my first point :

"True if there was a 'before'"

we know there is an after.
what we dont know is
a maybe.
a guess.
a theory.

"and on condition that there could be time without spatial content"

time does not exist.
it has no physical properties.

time is a word that is used for measurements.

like:
inch
centemeter
calorie
mole
newton , etc.

Maybe the very first "something" existed in the very first "word", in which case there would be no "before".

Alternatively, maybe there has always been something - maybe our universe arose from an infinite continuum that existed prior to the Big Bang.

infinite continuum

what a great description of GOD















3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
