I'm referring to time and space as statistical proofs that something is valuable across culture, time and societies. Just a matter of sampling: if you sample long enough from a distribution, you're going to create a sampling distribution that has the mean of the original one. If you sample long enough from all the civilizations and societies, you're going to find out that there's an underlying common ground they all are rooted into.

The fact that basically every civilization created a similar structure of beliefs around death; the fact that almost every civilization has a slightly different (but not fundamentally different) structure of religious beliefs.

The fact that almost every civilization that created complex networks of people and division of labour also created some sort of recommendation system in order to sort professionals by the value they bring to the civilization.

These facts testify that what I'm trusting is not my fellow humans, but the deterministic need for certainty, indexing and resource allocation criterias that mankind has. Then, you can choose to "believe" that it's a scam or not, but I guarantee you that anyone that tried to deviate from that tendency ended to:

a) recreate the same kind of system

b) didn't develop such a complex civilization and society than the one we have

I'm not arrogant enough to state that thousands of years of civilization and of humans inventing stuff based on these criterias is all garbage.
