I've been waiting for years to say that in context.

I apologize in advance for any condescending words i may utter.

1) Belief in God is not necessarily a lie or a myth. However, a theory that states "X happens because God made it that way." is of no scientific benefit for at least two reasons: One, it cannot be disproven. Two, such a theory could be used to explain absolutely anything: It has infinite explanatory powers, which means it has no predictive abilities. Such a theory is not a lie, a half-truth, or a myth, it is just scientifically useless.

2) If you google "Superstition in the pigeon" you may find it a fascinating read. In a famous study by B.F. Skinner, hungry pigeons were shown to develop "superstitious" and "ritulistic" behaviors simply by being fed small morsels of food at completely random intervals. In my humble opinion it is an enlightening perspective on human behavior, and although it may be a bit of a stretch, that study tells me that humans are naturally superstituous and ritulistic. I'd be genuinely surprised if we were able to let go of our religious beliefs.

3) To a believing Christian, using the words "magical sky wizards" to refer to God and calling their beliefs lies and myths only advertises deliberate irreverence. Furthermore, calling people that believe in God nut jobs is extremely rude and disrespectful. If you'd like to be thought of as an arrogant, ignorant, militant athiest or you'd like to start a fight, those are great ways to do it.

4) Indoctrinating children with religious beliefs does not necessarily mean that they will believe them. I can only give you my word i'm living proof of that.
