Enduring the elements, long distance running (no, it's not weightlessness, it's overcoming fatigue, muscle spasms, etc. I have read of this too), etc. is not the same as creating fireballs, controlling lightning, etc. Rain dances have been in existence for thousands of years and while on the surface they appear to be to bring rain and comfort, and yes, that is what they are believed to do, they primarily are the acts of desperate people seeking some sort of comfort.
We didn't "forget" anything.
