Most of the times as in the Help Center tells, on-topic stuff is about human-related facts, say: cultures, languages, famous people, political-related, human prehistory. Meanwhile, the item Historical Facts makes me think about stuff mankind has somehow recorded.
If I interpreted it right, stuff like asking about archeological facts/findings does not seem to be on-topic.
Up to what extend am I right or wrong about what I said? Is this the place to ask, say, the archeological or geological facts about something which is not a priori related with human behavior? Or should I ask about those when human-related facts had place?
