The tone implies that you think the first statement is wrong in some way, but it's still not clear why. Their comment was bring it back around to the original topic of the thread: the entire scope of homo sapiens sapiens existence and how long it took us to figure things out in relation to that. You're trying to limit the scope to just the time period where the rest of the necessary knowledge had been discovered, while everyone else is counting the discovery of that background knowledge as part of the process.
