Good point. But that's why the first wird of the sentence is IF...<quoted text>
There is no physical or practical evidence for the subject of the paragraph
The very first phrase is open to question. Where does that babble say that god is outside nature? If that first phrase is an assumption or personal opinion then the rest of the passage must also be considered and assumption or personal opinion
It makes assumptions based on misunderstanding of the general nature of atheism.
And the guy questions atheistic reason?
Open your mind a little.
Understand that not everything is or can be in the realm of science.
