How can we be sure that all religions are wrong?

Yes I agree, that is why I find Joseph smith, "the prophet Mohammed and this new Jesus to all be saviors. Would you like to prey with me that this new Jesus is guided by the father?

When you find yourself saying 'wrong', no 'part wrong', no 'wrong if interpreted such-and-such way'...and especially when you don't define your main term 'religion' [does conviction that there is a God mean 'religion'] ....and finally when you use 'all' -- consider yourself mindless. In a moderated debate you would have tinnitus‎ from the judges ringing the bell

I think all superstitions are "wrong" in that, by definition, they have no "scientific support, but religions exist almost universally because they generally serve social functions, i.e., almost every society practices some kind of "religion", but not every individual does even though they can serve psychological functions.

Social functions, and I think the need to believe there is something more powerful than humans. Who/what created the universe.

And where does that need come from?
What evolutionary function does it serve? (Since that is what supposedly drives everything)

It's a human trait; it's in the genes, so to speak. It has nothing to do with evolutionary function. Primitive humans, no matter where they were located, sought and believed in some sort of god(s).
In Egypt, kings declared themselves as god. There were also many mythological gods in Egypt. Some were even the fore runners of the Christian god.

Do you have any idea how contradictory that statement is to positions you have taken in the past?

According to the scientists you have pinned your beliefs on, genes have EVERYTHING to do with evolution.
So what is your explaination for this genetic predisposition to believe in God?

Genes have everything to do with human evolution, but we're talking about the sociological aspect of human behavior.
Not all cultures have religion. That's a fact.

Very funny CI. You just said in your last post:


But tell me more about these cultures that have no God.

Monotheism has the claim to man's oldest religious belief.

The question would clear up if you read
https://www.firstthings.com/blogs/leithart/2015/02/original-monotheism

":Winfried Corduan’s In the Beginning God is largely an effort to rehabilitate the reputation and theory of Catholic linguist Wilhelm Schmidt, whose 12-volume Der Ursprung der Gottesidee (1912-54) argued that monotheism was the original form of religious belief. "

It would have to be. Did you ever see something so elegant as 'all this' designed by a committee?

And this is the source of the term UNIverse, the conviction of even pagans that there is a One Mind behind all that is.

I saw other articles about cultures without theism, but I found this one to post here: http://atheism.about.com/od/atheismhistory/a/PrimitiveAtheismSkepticism.htm

Some times our life long beliefs in some things can change when we learn that our previous assumptions were wrong.

I'm not so fixed in my beliefs that I won't change with more information about any subject.

But this is more a matter of science than of belief. All Christianity's claims revolve on the one question, Is Jesus the Son of God, whereas science always has to adjust all data and theories to be compatible, hence that amazing but true statement of Polanyi's :

" a series of observations which at one time were held to be important scientific facts, were a few years later completely discredited and committed to oblivion, without ever having been disproved or indeed newly tested, simply because the conceptual framework of science had meanwhile so altered that the facts no longer appeared credible."

And his friend Einstein also had this view of the naivete of almost all his contemporaries
"How does it happen that a properly endowed natural scientist comes to concern himself with epistemology? Is there no more valuable work in his specialty? I hear many of my colleagues saying, and I sense it from many more, that they feel this way. I cannot share this sentiment. ... Concepts that have proven useful in ordering things easily achieve such an authority over us that we forget their earthly origins and accept them as unalterable givens. Thus they come to be stamped as 'necessities of thought,' 'a priori givens,' etc."

"The path of scientific advance is often made impassable for a long time through such errors.
" Einstein, 1916, "Memorial notice for Ernst Mach," Physikalische Zeitschrift 17: 101-02.

is a statement made without any evidence. Is the tooth fairy the son of the easter bunny? There's no way to prove it with evidence. It's only a statement.

Do you realize that you contradict yourself. You argument logically is that reason finds this undecidable yet you take it that the opposite way, that reason decides against.

The question is, IS there a God. And the answer is before religion per se.

Have you ever studied logic? Proving a negative is almost impossible. Most require objective evidence before it is proven to be factual. Religion is based on faith and faith only.

Like a good beer you only need ONE. My idea is that whatever gets you higher, makes you better is the religion for now.

My favorite high is from adrenalin but it's not enough.
I still need a reason for it all.
