Alas, you make many assertions without backing any of them up. Your claim that the gospels were written centuries later is falsified by the many other documents where Church fathers quoted from them in the first and second centuries. Your comments on Dr. Luke are particularly egregious. He was a non-Jewish resident of Troas in Asia minor who met Paul in the middle of his second missionary journey. The narrative changes from third person to first person when Luke joined Paul's missionary team right here in Acts 16:10

Paul and his companions traveled throughout the region of Phrygia and Galatia, having been kept by the Holy Spirit from preaching the word in the province of Asia. When they came to the border of Mysia, they tried to enter Bithynia, but the Spirit of Jesus would not allow them to. So they passed by Mysia and went down to Troas. During the night Paul had a vision of a man of Macedonia standing and begging him, "Come over to Macedonia and help us." After Paul had seen the vision, we got ready at once to leave for Macedonia, concluding that God had called us to preach the gospel to them.

So Luke indeed was an eyewitness to everything that happened after that. The rest of his account can be best described as a documentary produced by a first century "investigative reporter." There is no more credible way for us to learn anything than having a professional investigator look into it for us. Being an "embedded reporter" traveling with the Apostle Paul for many years puts Dr. Luke in the perfect position to interview anybody and everybody in the early Christian community. You could simply not ask for a better witness/reporter/historian. And Luke was also certified by Sir Ramsay as a top tier historian based on his independent assessment of the accuracy of Luke's works.

One can always demand still more proof, but in the end we have to settle for what history will give us. There is no other source of historical data more credible in all of history than the meticulous accounts of Dr. Luke. The mere fact that you would reject such first rate testimony tells me that nothing will satisfy you. I am quite sure that none of the references you keep promising to reveal will have anywhere near the pedigree of Dr. Luke and the other apostles.

So far 100% of your case is based on claims that Jesus' hand picked disciples did not write the documents attributed to them and that there is therefore no record of what they heard Jesus say during the 3.5 years they studied under Him before spending the next several decades spreading what they had learned. It's time for us to see your proof of such bold and unsubstantiated claims.
