read Yuval Harari's "Sapiens"

It might be a matter of definition. We can, and have, proven that all religious texts etc. were composed and written by people (coincidentally most of these people were men) and in this sense were man made. Almost all claim that an invisible, undetectable, and immaterial being told them what or about what to write. Pastafarians, on the other hand, admit that they just made it up, hence are the only provably honest religion.

Ummm what's your alternative?

What proof is there that it's anything else?

How about reason as a means? Name any concept that is NOT of human origin. The proof burden would be then where it belongs; on the part of the propagator.

It's very interesting.

The fact that there is, nor ever has been, any evidence, facts or data to support the claim of the existence of any god(s), is proof enough that god(s) is a product of man's imagination.

Welcome to the asylum. Enjoy your stay.

It's been proved to be man-made, repeatedly.
The believers refuse to accept that.

Religions are organizations. Organizations are created by human beings. Not that complicated.

Everything in religion tells us it is man made. If you study the catholic church history you'll get there.

I don't think natural science can prove it but I'm hopeful that psychology will do it.

The faithfools don't accept science, they don't accept reason, they don't accept modern times, they do not accept the reality...... how would they accept the proof the God is man-made?

A woman in the U.S. just saw Jesus standing in the burning spire of Notre Dame on TV. This is in 2019? The faithfools see Jesus in bread toast. They see Mother Mary crying blood. All this defies logic and reason. You cannot convert the stupid. Stupid is by choice. Once they have made it, they cannot be changed. They must die out.

Religion is a human practice, which is man made, but religion is not belief nor faith and those who have faith may claim a 'calling' or a demand which they feel, and of which nothing (really) can be said.

I don't think so. Common sense to one person isn't the same for all of mankind.

Like whom else is in the race?

Only if you have commons sense.

We can make our own religion. That would prove it.

Religion is man made.

The idea of divinity behind those religions is a lot more troublesome as they often are too far removed from what we know as reality to conclusively disprove.

For example. I believe in 'Dave', a 3-headed giant ostrich like being existing in another dimension who created this universe when he sneezed.

Sure, it is a religion with just one follower. But prove me wrong.

You mean like, maybe religion is force of nature?

Just ask a group of Humans to stop talking about god for a year. I have not tried it but I would wager that god disappears.

Scientology

It's self evident.

Simple. Religion did not exist prior to lthe time that evolution produced the modern homo sapien.

No need for proof! Who invented them then, the penguins, the monkeys?
