We have good evidence that it used to be like English b (voiced bilabial plosive):

That's just one example. Native speakers are usually the worst at understanding and explaining their own language.

Yes I know about the Erasmus pronunciation and that it does not conform to how we talk nowadays. And I know most Greeks haven't ever heard about his theory. And I say theory because not everyone agrees with his proposed pronunciation.
But this here is another matter. Biblical texts are not in ancient Greek.
Edit: I actually said that the biblical texts are not in ancient Greek (in that the language had evolved from the time of Plato and other such texts) but to be honest I wasn't really sure about my statement. I tried to do a quick research and I might have been mistaken.
However about this particular prayer, although it is of course not in modern Greek, I do not think there are particular hard passages that are not understood without knowing any ancient Greek.
For most Greek speakers texts from this time are mostly legible, words like epiousios not withstanding.
Additionally I would like to point out that pronunciation has little to do with comprehension of written texts.
Is this true? As someone who studied classical Greek, I can mostly understand NT Koine OK, but most of modern Greek goes right over my head. Conversely (anecdote alert) I watched a YouTube video where a Greek guy took ancient texts out onto the streets of Athens and asked people to make sense of them; most people giggled self-consciously and admitted that while they had studied them in school they were able to make very little headway in actual translations.
Edit: so my point is that, to my naïve eye, Koine seems much closer to Attic than to Modern, and hence I'd expect modern Greeks to struggle with it - but would be very interested in being proved wrong :)
But still it was an academic exercise, it required attention and some time, it was far easier than classical texts yet not something you can do in the street on the fly.
I may have to pull back from mostly legible to mostly decode-able. ;)
Also, /b/, /β/ and /v/ have the tendency to get swap with each other in lots of languages, and most people fail to distinguish them apart unless their language imposes a clear distinction among them. See for instance how Italian or English distinguish /b/ from /v/, while /b/, /β/ and /v/ are all basically the same thing for a Spanish speaker.
This familiarity didn't end overnight and as these things often do they live on in a long tail, see for example Russian influence in many ex-soviet republics which is only waning with the youngest generations, or for example German influence that lasted in northern Croatia way longer than the austro-hungarian domination.
That said, linguistics is full of traps. The common person on the street makes all sorts of assumption based on modern facets, often inverting the relationship between Prestige/low-education/provinciality with historical language change, i.e. often assuming that the poor illiterate provincial people are those who talk badly and distort the language, while in reality they often preserve archaic forms in some cases (while innovating in others).
An example from contemporary coastal Tuscany in Italy: in the local dialect the word for rabbit is "cunigliolo" while the offician Italian is "coniglio". If you ask a random person from the street they would tell you that "cunigliolo" is not only an uneducated form but actually a silly deformation of the right word and that it's obviously so, because the suffix "-olo" sounds funny (probably because of the influence of the names of the seven dwarves in Italian, brontolo, cucciolo, mammolo, pisolo, ... all designed to sound cute to the ear of a modern italiano speaker).
Turns out that the latin word for rabbit is "cuniculus".
Now, did I say that linguistics is tricky? Turns out that the "-olo" suffix has been added to other words as well, like "ragnolo" which has no etymological explaination. They could be an innovation to regularize the perceived "funny local way of saying rabbit", perhaps modeled on the 7 dwarves, or not. Perhaps cunigliolo etymology is also wrong and I'm grasping at straws, but I think my main point still holds: don't trust the gut reaction of native speakers for anything other than their living language.
—-edit to add comment on pronunciation of β
On the specific pronunciation subject, I am no expert in the matter but I do wonder how that reconciles with the fact that the letters μπ make the sound b in Greek and that combination of letters is not modern but has been in Ancient Greek words too, such as in εμπνέω.
For example she had a hard time expressing when does she say “oui” and when does she say “si”; being such a basic word (probably learnt at age 2), she never had to sit and try to infer the rule explicitly. Whereas every french-as-second-language speaker, this is a basic (explicit) rule that has been discussed in class and memorized before being internalized.
And having the rules more explicitly in the head enables hard reasoning over them, which goes beyond intuitiveness in some contexts.
It's possible that "μπ" was not pronounced "b" as today, in ancient times, but as "mp". For example, I think Cypriot Greeks tend to pronounce another consontant dipthong, "ντ" as "nt" rather than "d".
I'd find it fascinating that you would have encountered these discrepancies often enough to form such an opinion, assuming you're not involved in studies of or adjacent to ancient greek.
Can you highlight what OP got wrong?
Unfortunately, an inflammatory grandiose generalization like "native speakers are the worst at understanding their own language" is likely to derail a thread altogether and turn itself into the (much less interesting) topic, so please let's all try to edit those out of our posts to HN.
To be fair though, i guess this happens in any language/ethnicity so it is better to leave science to the experts/scientists and take their opinion. And ancient Greek scientists are not necessarily Greeks as much as any random Greek speaker is not a linguist.
