All the problems of the world arise from man confusing "nature made" with "man made". Including religion:
Man built a house from wood and stone. Then, that man LOOKED AT THE HOUSE, saying, I built this house. Then, that same man looked at the forest, at the rivers, at the sky and asked "who built this?". So suddenly the confusion arised, because that man thought, this house that I HAVE BUILT, would not exist otherwise, so who built the world (who would not exist otherwise either). Failing to realize that the world, and even himself, the MAN, had built themselves, without help nor intervention, and that HE, the MAN, was the first creation, aware of creation.
Then he became preoccupied with which part of creation that was, was it the beginning, the end, the middle, the upper the lower, with who created what...rather than focusing on the fact that he was creation noticing creation. It is indeed the perfect occasion to confuse everything and our society has not missed a single trap that could have gotten them confused. Fell in them all, one by one.
How hard is it to stop there? That you are creation noticing creation? No need to make a God story also, because you are scared to notice. Just notice...and then die. Simple. Why look for more? There is nothing else. Just noticing and dying. It's what everybody's been doing since day one...noticing and dying. If you have trouble accepting "death" as the ultimate purpose, then the best compromise I can think of is that: The purpose of life is to notice and die.
Everything else is a fabrication, a concoction, an interpolation: It is a man made innovation! The purpose is to succeed in your career and to do good deeds. Says who?
The other confusion is between what a man IS and what HE DOES. "I am a lawyer", so here the daily activity of that man is confused with his identity, failing to notice he could have chosen any other profession while still being the same person:
This also comes from primitive Indian tribes where names were given as a function of what a man did, like Ghisu FastAxe, he was named that way because he was a quick handler of axes so his identity was confused with his doings. You can say well, a 35 y.o. lawyer is a different person from himself when he was 3 y.o., because they have nothing in common. Sure but, the reason why the lawyer doesn't touch a hot plate anymore, is because he did so when he was 3 and got burned. So it had to be the same person, WITHOUT any changes. The SAME.
You understand who you are when you say, I, the 35 y.o. lawyer and I, the 3 y.o. touching hot plates and getting burned, is one. Not two. It's the same thing, without a single difference. Then you understand the I, you understand who you are, and you are happy to just notice and die, because it's how it should be. Every animal is capable of doing it except human beings, because they think instead of noticing.
