Remember, I'm a Conservative Atheist...and I ask the same question about you!
I simply did something almost no one does: what is missing that should be there, what would be different if Jesus did exist?
I asked:
Why were there early Christian communities with no concept of Jesus except as a spirit? You've probably never been told about those.
Why there is a weird absence from Paul's writings concerning any biographical info about Jesus. No virgin birth, no miracles, no parables.
What order the books of the Bible were written and why. I noticed that biographical information about Jesus came about only AFTER Paul had been preaching about his visions.
Why there were so many discordant gospels and "Christs" that were incongruent with Paul's teachings. Rival "false" apostles. No internet, no phones, why so many different stories so soon if these groups had been founded by the 12 going into the world to preach the gospel.
Why Mark ended in 16:8 and why the remaining verses were added 100 years later.
Why each gospel written after Mark (Matthew, Luke, John in that order) gained details, corrected Mark's wrong geographical information, expanded the story, gained details, and branched out in mutually incompatible directions.
Why Jesus supposedly cleansed the temple at the end of his ministry in Mark, Matthew, and Luke but did it at the beginning of his ministry in John (note that the temple covered about 25 acres and Josephus reported that during Passover, 500-600 Roman soldiers were stationed nearby and 40 or so Levite guards were stationed there, making such a spectacle implausible).
Why Paul's list of witnesses in 1 Cor 15:5-8 conflicted with the Gospel accounts.
Why there are so many "dying and rising" saviors in so many societies in history ... along with so many "virgin" births. Dozens.
Why were so many details about Jesus' trial that were inconsistent and why they appeared to be so blatantly fabricated.
Why Matthew did so much quote mining & still got things wrong.
Why the Testimonium Flavianum was so flawed -- early Church father Origen decried that Josephus never mentioned Jesus then, centuries later, after HIS OWN copy of Josephus' works were passed down to Eusebius, his "testimony" suddenly appeared. Note that Eusebius was a known forger of documents and was called out on it.
I found I couldn't trust anything in the Bible. That's the only place Jesus is mentioned. Other mentions are of Christians and various sects, not Jesus himself.
