I had an idea that most of the history I learned in school was just lies at a very young age, probably about 4th grade. Things just do not add up when they said a certain king willingly gave the throne to a civil engineer, or a certain country won or lose a battle because of their belief or philosophy. A lot of them sound like lies to me, the further back it was the weirder it sound.
I was more convinced later when others on the internet found evidence not in the main history that those histories were suspicious. Carbon dating, genetic info, financial records of food prices, fossils in different layers on earth, civilian diaries, the naming of historic sites, etc.
I am more convinced than before that we are just repeating what our ancestors did in the past, and history is just repeating itself with a slightly different variation each time, and most importantly history was written by the winners, and I am not going to worship someone as good or evil just because they win or lose. You can say I am a history nerd in a different way, and I gave up using history as a proof of anything.
