My suggestion, don't attempt to answer someone presenting anything as science if you don't quite understand the science yourself. Many times, theists will attempt to point to current science to supposedly support their claim that science in some way supports the existence of a god. Some will go as far as to say that it actually is evidence for a god. All of this is of course nonsense. Science is necessarily agnostic when it comes to anything about a god. Science is a limited way of knowing. We limit ourselves to natural causes because we test our ideas against the natural world. The way we test a hypothesis to hold constant certain variables. If a god can do anything it wants, you cannot hold his/it's actions constant. Any outcome we get is compatible with the actions of an omnipotent or supernatural cause, therefore these things are untestable.
Most of the time, they will distort what science actually claims. Just about every time I see these types of arguments, they are merely straw men.
