What is the story of Atlantis after it fell into the ocean? Is there any stories after its demise?

After the fall of Atlantis, the remaining people spread across the globe in parts of north America and Egypt and began the cycle of human develop and empirical rule again. That's where the theory of the great pyramid of Giza came to place, where its the most geographically detailed and precised structure in the world. That was their last monumental discovery and they eventually died out and their civilization was destroyed. As for the Americans, they also have the same similarities culture wise compared to the Egyptians. They said that its no coincidence, someone must have known or something must have happened. I don't know if its true, but many prophets prophetical interpreted the existence of Atlantis. Also the Greek philosopher, I forgot his name also wrote a historical background story of mankind and specifically added that Atlantis was a booming civilization that actually existed.
