Facts have real-world significance if it becomes part of a cultural propaganda. If one were less friendly they would say you have been "brainwashed" to believe that the European cultures (and their descendants) are entitled to more credit than they deserve in advancing the technology of humanity. Maybe, just maybe, people would be more humble if they knew that we have all learned from each other, and not, as the narrative goes, invented everything merely from a stroke of genius.

Of course, it doesn't really matter for a learned person who has the natural curiosity to figure things out (presumably that includes you), since these people aren't often affected by dogma or rigid conceptions anyway, but the other 99% have no clue, and it's probably easier to state facts than to teach people curiosity.
