I actually thought this on my own after watching some history channel series about the first millennium AD, roman empire, whatever. I was struck at the similarity of some events that were supposedly separated by hundreds of years, almost as if it was the same story told from a different perspective.

Then I found Anatoly Fomenko, Gunnar Heinsohn, Herbert Illig, etc had investigated this.

I'll add another link to the two already shared by sister responses: https://www.q-mag.org/the-1st-millennium-a-d-chronology-cont...

Definitely a fascinating topic. I emerged from that rabbit hole unconvinced but definitely with far more doubt about the reliability of the mainstream chronology.
