And even if civilization “collapsed” it’s not like our scientific and organizational knowledge would have disappeared, making it ridiculously easier to rebuild than it was to build in the first place.
I’m a bit sceptical about that. Compare the technological level of Europe in AD 100 with that of Europe in AD 700.
Which part of “Europe” are you talking about? Western peripheries of Roman Empire got somewhat backwards, and that was after massive demographic collapse of late Antiquity, the rest of Europe didn’t really change all that drastically, or even progressed quite a lot.
