Origin of he universe

When some scientists have given an explanation for the origin of the universe due to quantum energy fluctuation in a void, was it that their sole purpose was just to show how the universe had actually originated? No, they were having one more open agenda and some scientists are still very much vocal about it: they want to send a message to all sorts of superstitious believers all over the world, so that they can forever arise from their dogmatic slumber, that this universe does not need any kind of God in any way.
