I could argue that in some respects belief makes reality, but I am not sure that I am mentally up for it right now.
As for the intangibles of things like religion, sure, belief makes reality iow a number of worshipers is all that is required for a deity to exist. No particular number of worshipers required, just a number of them.
To quote Galileo, "In matters of science, the authority of a thousand is not worth the humble reasoning of a single individual." People who say that belief makes reality must not believe in absolute truth...but wait, if enough people believe in absolute truth, does that make it real? If enough people clap their hands will Tinkerbell live?
