Superman exists?

A few days ago I was reading about the discover of "kryptonite" mineral almost matching the properties of the fictitious mineral, a day after that I saw news about a earth like planet orbiting a red dwarf star, and I remembered a few days ago about a meteor shower.

So I know in astronomy when one see an object located many years-light from here, we are observing in this time the past time , centuries or thousands years, of the object because the delay in the travel of light so I was imagining about the possibility of some years ago someone in that earth like planet sent a spaceship, with his son aboard and at present time that planet exploded, and the spaceship arrived to our planet in the meteor shower.

I know it's fantasy, but when the comics describes three real events occurring in so little time
what is the probability of the events??

maybe soon someone will see the sky and tell us "it's a plane?"
