Less than a hundred years? That may seem like a small time compared to the thousands of years that have passed in the meantime. But we are talking about human beings, who at that time didn’t live more than 60 years. Imagine writing something that happened a lifetime ago and have people take it for fact.
Josephus wrote about Jesus about 60 years after the death of Jesus. And his works have been transcribed by Christians hundreds of years later, so it isn’t clear what was original and what wasn’t. The Christians most certainly made errors, embellishments and changes to the story. So even if there is a kernel of truth there, it’s impossible to know what was real now and most experts agree it’s fiction.
Tacitus wrote about Jesus about 80 years after the death of Jesus. Most experts think Tacitus wrote about Christians and what they believe, not as a description of what actually happened.
It seems to me you are under the impression of sudden media like today. It took a long time for widespread media at the time. They didn’t have social media, nor print presses. Every thing had to done by hand. Spreading the information within that time seems very accurate for the time. And Josephus died at 63. Not a big gap, but still a gap compared to what you’re saying. He was born around 37 AD (4 years after the death of Jesus). You’re telling me that he couldn’t have got real explanations of it through his life? If we’re going to say that, then all the people born a few years after WW1 are lying
