The people at the time knew they were religious texts rather than accounts of actual events.
Not true.
1. If they were never intended to be taken as anything other than myth, they would hardly survive as they did. Most religious texts did not. Yet we have very, very early copies or pieces of copies of the texts, indicating that from the beginning they were treated as something other than just religious stories.
2. The early church fathers, some of whom personally knew Jesus' disciples, show an awareness of these texts and of the person of Jesus as a historical person.
3. Paul knew Jesus brother, and Josephus at least knew of him, meaning that Jesus' was considered well known enough even in the first century (not long after his death) to be used as a kin identifier for James in Josephus.
4. As I said, these texts do not resemble mythic texts. I cited for you a number of studies which go into this issue in great detail. Rather, they resemble ancient biography
5. Mythic religious texts do not posit founders who lived only a few years ago, within living memory. They place their founders in some time long past, so it is impossible to prove false. Jesus is placed in a specific time and place.
Believers that viewed these mythologies as actual accounts came much later
What evidence do you have for this? None.
and there's no reason to trust your view of history anymore than your view of early Christianity.
Actually, given the fact that I have studied it a great deal, and you know nothing about it, that is a pretty good reason. But you don't have to trust me. You could read virtually any scholar in a relevant field, and although you would get different answers to various issues, they would all (with one exception, two if you count classical studies), regardless of religious persuasion, tell you we have LOTS of evidence attesting to Jesus' historicity. Which is why virtually every single mythicist promoter are laypersons.
No this story is not a history text by any stretch and neither is any other uncorroborated storied account considered historical.
Here again we have you opinion backed up with zero study of ancient history.
It's one and the same basic story retold and rewritten, and yes, Matthew and Luke copied Mark almost word for word
Then what is Q? Or M? or L?
that's why they are called synoptic, they are the same story
synoptic comes from the greek and means "seen together" in that these three agree more with each other than with John. It does not meant Matthew and Luke copied Mark, although they both probably used him.
If there were eyewitnesses we'd have very different stories, but we don't. There were no eye witnesses.
How so? If the eyewitnesses all agreed on what happened, the stories would be very similar? What a foolish argument.
And again, the fact that Luke used Mark and Q (oral or written) does not mean he did not have access to the tradition from eyewitnesses (which he states in Luke, and in Acts he is presents at certain points). Copying someone else's text wouldn't be considered bad form. If Luke wanted to write a
bio of Jesus, it makes perfect sense that he would begin with one already circulating, and add to it what he thought was important.
Moreover, Paul too met and learned from the eyewitnesses (Peter and James Jesus' brother, among others). And although he occasionally alludes to or explicitly cites Jesus' teachings which he received, he was not interested in a 'life" of Jesus and so barely touched on it.
