Reasons for thinking that no notes were taken while Jesus and apostles were teaching?

[Longfellow]

Yes, actual notes

You would expect notes written on waxed surfaces to survive for 2000 years?

or someone later referencing the notes or stating there were notes.

We have that.

It has nothing to do with my expectations.
You'd just have to have some remnants of notes in whatever form, if you want to point to something and say "look, here's some evidence of notes"

We have that.

Great!
