I made no mistake.
Your mistake was believing your knowledge of history superior to the history books and the historians who research and write them.
"Those historians should know better" you said.

All I did was to repeat what I read.
I was ridiculed for that by people who had read nothing written for at least twenty years!

Likewise astrophysics and cosmology.
I follow the debate but do not consider myself qualified to contribute.
All have said here is mainstream current understanding.
