anatomically modern human beings have been on this planet for roughly 200,000 years. And even though that's a small fraction of the amount of time the Earth has been around, which is over four billion years, on a human scale, it's an incredibly long amount of time. Just to put it in perspective, if this is present time, if you wanted to put, when was the Roman Empire, well, if we're talking about about 2,000 years ago, it would show up on our timeline right about, right about there. If you wanted to talk about when the pyramids were constructed, it would be right about there. You can hardly see the time difference between now and several thousand years ago. If you wanna see how long we've had writing, about 5,000 years is our current best estimate. Once again, it barely shows up on this timeline.
