If humanity moves to another solar system in the future, how will religions adapt to the change?

There are different religions in the world that have stories and teachings about Earth's celestial bodies (Moon, Sun, Planets) and the Earth itself.

Will we have to rewrite or erase those religious writings to work on another planet with its own celestial bodies and the new planet itself?
