When I was 4 my brother and I used the garden hose for hours, spraying the sidewalk, trees, etc. My dad got mad at us for wasting water and since storm clouds were gathering, for some reason he told us that we had "made it rain." Until age 10 I firmly believed that spraying the water into the air had caused the clouds to form and caused the resultant rain, and I didn't completely let go of this belief until about age 15.
