Life After Death an Imaginary or Realism ?

Hell, heaven and kingdom of lord--these are the imaginary thoughts of the people and such thoughts will remain present where people will reside. There is life (people) on this earth and our rockets and satellites searched the space here and there but they did not report the existence of any such hell, heaven or kingdom of lord. There are so many galaxies or to say so many independent universes and they should have their own-hell, heaven or kingdom of lord .so in our universe in which sun has the center stage, there lays no hell, heaven or kingdom of lord as reported by the satellites. These are the religious terms to exploit the masses and to keep their faith in a specific religion intact. 
Further, in the theory of probability, the players are definite. Here the existence or non-existence both the players are not definite, then how can theory of probability be applied in this case? Such terms have no place in the domain of reasoning.
