In some way, we are all wrong. Just because there are many different religions doesn't mean that one is completely right and the rest are completely wrong.
If all religions stopped, and we documented it's removal, and accurately showed our descendants the errors and effects of it's way, religion would not resurrect. The only "religions" that would exist would be ones that are more of a way of life, like mine.
Yes it would. Because
all religions are ways of life. That is the whole point. If you think that you know everything about religion, or at least enough to know exactly why it's wrong and how to explain to others why it's wrong, you know pretty much nothing about religion.
The argument that religion and humanity are inseparable concepts is lunacy. Would you say a tree is religious? How about a moose? What is its religion? If not, why do humans need religion and not any other species?
I said humanity. We are not trees. We are not moose. Why do we need religion? Because it speaks in a language we cannot explain, cannot fully understand, nor fully appreciate, and yet is as important to us as life itself. Why? If we do not have it, what makes us different than the trees or the moose?
