every person who finished some school should understand that speaking about motion without reference frame is meaningless.
Is such frame is proper to Earth (yeah, go google what proper frame is) then the Sun does revolve around Earth.
If the frame is not proper to Earth or Sun then they both rotate around common center of mass which is (relatively) near Sun’s center but does not coincide with it.
