No, just following your logic sir,
A world without religion would be a world without God and without God, you cannot have human beings.
I get the point of your message that if we all just got along and did not have religion to divide us...but the statement is self defeating and doesn't work because if there was no religion, it would mean there is no God who would have created human beings, if no God to create human beings, no human beings and thus we would not be having this conversation.
The fact we have religion shows there is a God who created people with their ultimate purpose to have fellowship with him, but we do not have such a fellowship as yet so there is a void in the human heart. Religions are groping and desperate attempts to fill that divine void in all of us.
Christianity however is God Himself, coming down as a human being and paying the necessary price to make that fellowship with Him possible.
