Why did the Starship SN8 landing fail?

On December 9, 2020, humanity witnessed its first glimpse of SpaceX’s Starship, which will take humans to Mars. It was a successful test; however, the prototype failed to land and crashed in a spectacular fashion, erupting in a fireball. What went wrong and how to explain what we saw?

Thank You so much for the information !

considering that at least one raptor was producing thrust you would have thought there would have been a mechanism capable of diverting some of the thrust force produced from the working raptor into adding pressure to the fuel tank. Perhaps this will be a design consideration for the future.

It didn't fail, but sadly your title did.
