Flat Earth Proof

Many images of far away objects have been posted all over the internet, showing that there is no curvature to the earth.  In this case, we can see the Chicago Skyline from across Lake Michigan, at a distance of 59 miles. This particular example is very compelling, since the expected curvature on a spherical Earth would occlude every single building in the skyline – 100%.  Yet we see the ENTIRE skyline.  How is this possible on s spherical object?  It is not.
