Is human consciousness creating reality?

Seems ripe for a sci fi concept: if the coherent conscious model of observers was able to shape the universe (rather than merely observe some “objective” truth about it), conceivably a society that believed in the daily intervention of gods could actually see that happen (not merely interpret it as such) in a way we might consider inconsistent with our understanding of physics. You just need faith as they say.
In retrospect, that concept has perhaps already been executed in Gaiman’s American Gods.
Indicators might be that groups of physicists believe in new tiny particles and then discover them.
Depending on how powerful the effect is; it might have interesting implications.
Consider that despite all the odds we are still here as a species. For example I sometimes imagine that the world was destroyed by a global atomic war in the 1980s but since we all rejected that bleak reality - we have this current reality instead.
