Caelolatry

Caelolatry is the worship of the sky. Sky is the direction of God's home and worshippers point the sign up in the sky to summon God. Sky is the exit to the outer space and heaven. The sky is decorated with clouds, stars, changing phases of the moon, and sometimes comets and meteors, in addition to life-giving sun.
