There are in fact lots of pyramids and flatter proto-pyramids of various sizes! The total number is probably in the thousands, I believe. Many have also been demolished in ancient times so the stones could be reused. For example the pyramid of Djedefre, son of Khufu who built the famous Great Pyramid. Instead of competing on size, the son made a smaller pyramid of more beautiful stone, but unfortunately the stone was too valuable to let stand and was repurposed over millennia: https://en.wikipedia.org/wiki/Pyramid_of_Djedefre https://en.wikipedia.org/wiki/Pyramid_of_Djedefre
