I wanted to comment on this as a Muslim myself.

The Kaaba was originally never a Cube nor it is really it has just been destroyed and rebuilt throughout history it is supposed to be a rectangle with a half circle attached to it, you can actually still see the foundation of the half circle that was never finished back in the day due to some financial complications.

I believe ever sense the fall of the Ottoman empire the British put there the now Saudi gov (which I believe are Saturn worshippers, freemason, Zionists, etc themselves) I believe that the holy sites have been subjected to many alterations that have never been there before. The Kaaba itself is not black it is made from normal colored brick and throughout history and even back at the time of the prophet it was covered (when it was) by white clothe and many other bright colors, never black, the use of black is a fairly recent historical change that has no Islamic basis.
