Isn't money a big mystery and bullshit invented by people?

It is just a digital numbers or a paper. But a very very hard to get it in this world. And when you get it, it can change everything in life. But to get it, you have to put your everything to the table, so hard, and it is still not guaranteed to make it. So weird. I can not figure out the logic of money in this world. Why is everything depend on this bullshit.
