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. How long have we had agriculture? Well, 10 to 15,000 years. Once again, it's a small fraction of this.
