This isn't even a difference of opinion argument, this is science vs religion.
In any case, the initial argument is completely unfounded on any religious or scientific principles so there is no reason to be offended.
I view religion as being the study of the spiritual world, and science as being a study of the physical world. Both change over time, and both are people searching for answers.
