The Breeze. Now that's Something I Can Believe In

Last Sunday, I tried to convince a group of children all age 8 and under that the reason the long thin banners in the sanctuary were gently rotating over their heads was because very small aliens on motorcycles zipping around in the air would occasionally grab hold of them as they passed by, giving them a little spin.
They weren't buying it. Not a one of them.
Nor did they believe that the guy in the sound booth had a control panel with buttons and levers that he would push every now and again when he was bored (perhaps during the sermon) to make them turn.
The only theory they believed in, the only one they voted for was the one that I also think is really the truth—that air currents were doing the trick. One older pre-teen sitting with his parents voted for the alien idea, but he's at that contrary age.
I was surprised and impressed with the children's wisdom, even at that tender age. I thought the sound booth idea at least had a small hint of believability.
Though I can't see air, I believe in the breeze because I have experienced it in other ways so very often. I'm not sure we should believe in anything that we haven't had direct experience of—probably repeated experience at that.
But that's just what I believe.
