Ok and who is the author of this lie ?.....did the author of Luke is invented the lie or did he receive the lie from someone else?
Who says it's a single person?
Ever played the telephone game? Is it a single person in the chain that alters the story? Or is it rather each individual in the chain that misses / adds / changes a few details, which then accumulate as you move up the chain to end up with a story vastly different from the one it started out with?
I'm reminded of an incident when I was younger. There was a bakery a couple houses down the road from where I lived. One day, an ambulance and a firetruck were parked in front of the bakery. Some smoke was coming out of the boiler. There was some plastic melting going on etc. If left alone it would surely have started a fire. The fireman quickly resolved the problem and were on their way.
Couple days later I was at the local supermarket waiting in line. I overheard a conversation of some folks in front of me, discussing the event. After only a couple days, less then a week, the story had transformed into the bakery warehouse going up in flames and 2 people being taken to the hospital. I'm not joking. None of that actually happened. It was just
some smoke in the boiler. Nobody got hurt. Nobody got taken away. There wasn't a single flame to be seen.
Was this the result of a single person changing that into the story of the all out fire with 2 people taken to the hospital? Off course not. It was instead a prime example of the telephone game.
...this is what probably happened
There was a Jesus who did some stuff that the disciples and people around interpreted as miracles......the founded a new religion and the authors of the gospels assumed that the miracle claims where true......... Do you have a better hypothesis on what probably happened?
It's impossible to tell. Consider my above example. And that's only after a couple of DAYS, when eyewitnesses, like myself, were actually around to correct mistakes. Yet, the story acquired a life of its own anyway. Things were added that never took place. There was no fire. There were no victims. I know because I saw them all standing in the street. I saw the ambulance take off without anyone in it except the driver and his companion. Yet in only a matter of days, the story changed to include 2 hospitalizations that never occurred.
So.... Some things might be rooted in true events, other things might be rooted in real events and be attributed to Jesus even though it concerned someone else, some other things will be as false as can be,....
Also, you make quite the assumption by saying that the original eyewitnesses interpreted it as miracles. You have no evidence for this at all. The only thing you know, is that decades later, people spoke of miracles.
Just like after a couple of days, people spoke of folks having to be hospitalized in my example. And these people weren't people that were actually there - because the people present at the event all knew that nobody was taken to the hospital and that the whole thing was much ado about nothing. The ambulance was only there because it's procedure. This was a completely fabricated detail that entered the story in only a matter of days. Imagine what it would be like if that story lived a life of its own for DECADES. And that during a time of no modern media, where fact checking can take place in the public sphere. Go to the next village and nobody there can double check your story.
I agree miracles should be dismissed unless additional and conclusive evidence is provided (but irrelevant for the purpose of the OP)
What is the purpose of the OP?
Because you claim they are reliable history, but you have just pretty much excluded a whole bunch of it by removing all the miraculous bits.
So I think you should reformulate it.
Into something like "the gospels are reliable history when it concerns those parts that can actually be verified and confirmed
Which pretty much is simply stating the obvious.
It's like saying "Marvel is reliable history, as far as it concerns its references to verifiable events, places and people
". Well duh.
