Your witnesses propose to write about things they did not witness as if they were fact. Very little of the Old Testament was first hand and none of the disciples were at the birth. They absolutely are not reliable as to the divinity of Jesus or the circumstances of his birth. I would actually say they are flat lying about it to make him appear to satisfy a prophecy.
Edit. I should also point out that eyewitness testimony use often the most unreliable testimony of all
So, let's get this straight: You say the apostles (not to mention the hundreds of other eyewitnesses) are "flat out" lying about the religion of Christ. Let's consider Paul as a test case to see if your accusation holds up. We're introduced to Paul (called "Saul" at the time) in Acts chapter eight, where we find him approving the execution of Stephen, an avowed disciple of the Lord Jesus, and the first lying conspirator (according to your theory) to die a horrible death for the Great Lie (he was pummeled to death with rocks, by the way). All he had to do was to admit the lie and they would have spared him.
Afterwards, Saul continues to "breathe out slaughter" against the followers of Jesus, killing many and imprisoning men and women, simply because they said that Jesus was the Christ. It was a lie, but they died for it and went to prison for it anyway, because who really wants to live, right? The important thing for them was to perpetuate the lie.
In Acts chapter nine, we find Paul on the way to Damascus, with letters from the leaders of the Jews granting him authority to bind more followers of Jesus and drag them back to Jerusalem where they too will be killed and imprisoned for the Great Lie.
But a funny thing happed on Saul's journey. Before reaching the city, he decided to do a complete 180 and cast his lot with the conspirators and live the lie too! I guess he decided to do it for laughs, give up his exalted place in Jewish society, the riches and the fame, and live like a wanted criminal the rest of his life. So, he made up the story about Jesus appearing to him on the road and commissioning him as the apostle to the Gentiles, which just added to the laughs, because the Jews hated the Gentiles. Then he goes into the city and convinces Ananias-- an avowed follower of Jesus, who knew Paul had been had hounding, harassing, and murdering his fellow disciples--that he wants in on the lie too! And Ananias buys it! Then Paul goes to Jerusalem and convinces the other Apostles and disciples that he's a fellow conspirator! And they buy it too! The families of those whom Paul murdered and imprisoned for the Great Lie were there and accepted him with I open arms into the conspiracy! Then the crowd he used to run with, the one that supported him during his murderous rampage, ties to kill him.
Then Paul takes the charade on the road, on three different journeys, for after all he must have been a masochist, and he perpetuates the lie in every city he frequents. As a result of his stubbornness to cling to the Great Lie, he was beaten with rods three times, stoned and left for dead, shipwrecked tree times, and on one of them he clung to wreckage for a night and a day. On at least two different occasions he was imprisoned for what he taught, and the first one was for over two years. On five different occasions he received forty lashes from the Jews. He was "in perils often," and on and on we could go. And finally, he's led from the cell of his second imprisonment and is beheaded. All for the Great Lie! And you say you don't believe in miracles?
I apologize if it seems I am being flippant about this. Let me go further in depth. The eyewitnesses in question report a lot of hearsay which is not corroborated by any actual evidence and which they were not even saying they were present to witness. The historical record shows that Jesus probably did exist and was a preacher around 20 AD. He may or may not have been executed by the Romans. There is no actual proof that the person named as the writer is the actual writer of any of the Gospels, just faith and tradition. The generally accepted timeline is that these were anonymously written in the name of the particular apostle from oral traditions of the time. The oldest existing copy of any piece of any of them is a good 150-250 years after the fact. So, once you begin talking about eyewitnesses as proof you are going to have to corroborate that with other fact. The few Roman mentions of Jesus were way after the fact and are not corroborated with any evidence from Jesus' lifetime and shoudl be considered hearsay also.
Eyewitness testimony is not hearsay evidence. Hearsay testimony is "based on information a witness has heard from another person rather from direct personal knowledge or experience." Hearsay evidence, with few exceptions, is not admissible in most if not all courts in the world.
Where are you coming up with your information? First century Christians knew who authored the Gospels. Polycarp (69AD--155AD) was a disciple of John the apostle, who was an apostle of Christ and an eyewitness to His life, resurrection, and ascension. I'm pretty sure John knew who wrote the gospels, because he authored one of them and knew the authors of the other ones intimately. John no doubt passed on the information to Polycarp because Polycarp named the authors of the gospels. Actually, there is plenty of proof for the authorship of the gospels.
The oldest fragment of the gospels is actually the Rylands fragment of John's gospel (P52). It is generally dated between 125 AD and 175 AD. Some scholars date it to the late first century, so we're actually talking contemporary with or just a few decades removed from the authors. There was a time when radical critics dated the book of John from around 300 AD. They did this because John's gospel focuses on the deity of Christ, which they cannot abide, and a later date of authorship would lend credence to their theory that Christ's "supposed" deity wasn't believed by the early disciples but instead evolved over time. The discovery of this fragment put the kibosh on all that. What "historical record" are you referring to for your information?
What "other fact" would be acceptable to you for corroboration with eyewitness testimony to the veracity of the Bible as "proof"? I gave you fulfilled prophecy; you reject that, apparently. What other proof would suffice for you?
By the way Peter (an apostle of Jesus) said, "For we did not follow cleverly devised myths when we made known to you the power and coming of our LORD Jesus Christ, but we were EYEWITNESES of his majesty" (2 Pet. 1:16).
John, another apostle of Jesus, said, "That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon and have touched with our hands, concerning the word of life--the life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life" (1 John 1:1-2). So, the witnesses wrote about the facts that they witnessed, not "about things they did not witness as if they were fact" as you propose.
I have researched and I struggle to understand what this is proof of. That the Bible is like a palm reader who gives you generic "as long as the earth exists it will exist" prophecies and expects you to believe everything they say. If day and night ceased then of course the earth would cease to exist.
You said I couldn't prove the Bible is "right." This passage is right (the seasons come and go); therefore, the bible is right.
