That is simply not true - the earliest recorded marriages were not religious, they were a way of transferring property rights over women, forging alliances between different families and communities, and for producing and protecting bloodlines.
Religion didn't become involved for hundreds of years and the church didn't even recognise marriage as a sacrament until thousands of years after the first recorded marriages. In ancient Rome, just to name one of many examples, marriage was a civil affair governed by law, not religion.
It's impossible to take anything you say seriously if you're just going to shout demonstrably false nonsense from a position of complete ignorance.
