Benjamin Franklin was an outspoken atheist, and several of the founding fathers were Masons. They wanted to be free from religious tyranny, which is what America would become under the rule of ANY religion.
I know atheists like to name Benjamin Franklin as 'one of them', but I've never read anything in his writings that said he didn't believe in God. He did write a couple times about his distaste for organized religion, however that is not the same thing as not believing in God at all. Someone who asks for a divine intervention at the Constitutional Convention seems more likely to be a deist of some kind rather than an atheist. Not to mention the letters he wrote to atheist writers trying to dissuade them from circulating their views saying it would do more harm than good.
There isn't a smoking gun here or whatever... the only thing about Franklin's religious views that we know definitively is that they changed over time. As he matured and got older and became more educated and read more books, his views changed, away from religion and then back to it. At times he comes off as very 'hot' in regards to religion, other times a bit colder, but I have never seen anything from Franklin that says 'I don't believe there is a God.'
