ChatGPT: "Four score and seven years ago — which, by the way, is a very long time, a tremendous amount of time — our fathers brought forth on this continent a new nation. A nation founded on liberty, on freedom, on the idea that all men are created equal. And let me tell you, nobody had ever seen anything quite like it. It was a beautiful thing. Really beautiful. Some people say it was the greatest founding in the history of the world. And now we’re here, in Gettysburg, Pennsylvania, a place that’s become very famous, very important, and frankly, a place that deserves a lot of credit."

You're not wrong; that's pretty spot-on. :)
