there is no ‚‚truth" in the way people love to talk about it.
take just single event, in one 5 storys building. if there was 10 people, thats 10 stories, 10 fragments, 10 limited views. and they do not complete eachother, they create more empty places.

some people spend years to connect only 2 dots, and often they fail.
mainstream history is just a tool to grow assumptions, accept generalizations, and breed prejudices to pass them to next generations.
