Not even anywhere near that long. There have been humans for probably more than 200,000 years. Probably more. It gets confusing when you go back that far. But our written history only accounts for maybe 10,000 of those years. So 5% of total human history, if we take the minimum estimate of what it takes for us to be human. We have no evidence to support the fact that human advancement even lasts as long as written history. I mean, shit… the Romans had central heating and cement, and then they died out and we forgot how to do those things for 1,000 years. Our knowledge, and the acquisition of same is not exactly linear. Lots of fits and starts over the course of the various human civilizations that have occurred.
An important thing, about Homo Sapiens, is if we got the look of homo sapiens 200000 years ago, they still had the same brain volume and shape that their predecessors. It tooks some time for reach the modern brain volume/shape. Then previous homos steps was important too, in the discovery they made. So it’s quite reductice to limit humanity to homo sapiens.
Human advancement is only useful for as long as there are humans
