What does Deuteronomy 4:19 mean?

And when you look up and see the sun, moon, and stars—all the stuff in the sky—don't be tempted to worship them or serve them. The Lord your God put those things there for all people everywhere. Deuteronomy 4:19 - Modern Text Bible

(Moses warns against worshiping heavenly bodies, which God created for everyone, not as objects of worship.)
