In the original Planet of the Apes, Charlton Heston takes a one-way voyage in a starship because he hopes to find “something better” than our Earth.
Leftids still seek something better; and they have a starship, too.
Their voyage to Utopia will be aboard the all-powerful, all-devouring State. What would you even call it? Science and Government and brute force and madness all rolled into one!
But when you turn away from God, sooner or later you find an idol.
