Theistic religion stops rational thinking because if rational thinking were permitted most religions would evaporate. Theistic religion is the antithesis of rational thinking.
Theists claim we go to heaven after death.
Atheists claim we rot in the ground, and that’s it.
Neither side can prove anything.
Should we choose a theory which gives people hope, and encourages them to earn heaven through constructive behavior?
Or should we choose a theory which promises nothing as a reward for all our efforts?
We can’t separate these theories on the basis of fantasy, because both are fantasy. The theist thinks they know, the atheist thinks they know, but the truth is nobody has a clue what death is.
Which is the most rational theory?
