The only problem with this observation is that you are using your naked eye. Go and purchase a Nikon p900 camera that allows an 83x zoom, and what you will find is that you can zoom in and see the base of all of these buildings.
I know it seems unlikely... however, the law of perspective contains the 'Vanishing point' directly at the center where all lines converge.
Go get the camera or just youtube some videos where people prove this using the camera.
It's just an illusion using your naked eye. The buildings bases are visible when you zoom in!
