@dinoid - you simply asked the wrong question... It is not up to the non-believers to prove that religion is man made ...it IS up to the believers to prove that it is NOT !

Well who the hell else do you think "made" it??!!!

I am always amazed at how people just assume that "religion" refers to only Christianity, Islam or Judism. These 3 religions are barely 3,000 yrs old and humanity has been around millions of years.

Welcome to the asylum. Enjoy your stay.

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

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.

Is there any way that religion can be proved not to be man-made?

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

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

I think you just did...... just by posing that question and not getting killed instantly by lightning kind of proves that religion is man made.

Even most deists could agree with you that religion is socially constructed by humans. Also, you may want to read Peter Berger’s The Sacred Canopy to help you make your argument.

What proof is there that it's anything else?

Yes. Just read the Bible.

What other creature on this planet has the imagination, creativity, and need for attention than a human? Our history is filled with imaginative story-tellers as well as greedy power hungry people who lie, cheat, manipulate, and take advantage when the opportunity presents itself. Leaders past and present have taken advantage by creating fear with misinformation and used religion to gain control.
If a deity needs recognition and adulation then it would present itself to all humans, it is inefficient otherwise.

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

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.

read Yuval Harari's "Sapiens"

To the satisfaction of a fanatic? No.

To the satisfaction of a reasonable, reasoning person? Yes. I think that's how most of us ended up here.

To start with Mary wasn't a virgin.yes she had a child named him Jesus.he never died on the cross.so he never rose from dead.get the big picture.its all not true.

Whether or not there are any gods, and I believe there are not, religion itself is a social construct. If there were gods, they would continue to exist even if no one worshiped them, just as people worship even though there are no gods. Religions have more or less evolved over the millennia to fit the needs of their societies, so without knowing exactly when and where the first religion started, it would be impossible to prove the origin of religion, just as it is impossible to "prove" the nonexistence of gods or other unlikely beings.

YES. Just look at all the different beliefs and doctrines all coming from just as many scriptures. Either religion is man made or gods (if any) do not want to communicate with us.

Looking at the replies, i've had many a giggle and some inspiring answers. Thank you all for that.

I am now wondering what kind of feedback I would get if I asked how the design in nature came about?

wrong question. should be "Is there proof of a god-made religion?"
