True. But writers would want to separate alien planets from Earth, right? I mean, Krypton was not supposed to be a parallel Earth. They could have an equivalent to pizza, but it would be very different from our pizza. It would take a miraculous coincidence or someone stealing pizza from Earth to see pizza on another planet that is just like ours.
