Had his response been "because he's talking about evolutionary science!" That would be circular reasoning. However an evolutionary scientist would answer "because he's looking using factual data to back his assertion in the book claiming evolutionary science is correct." The http://circularreasoning.ytmnd.com IS circular reasoning because the Bible depends on God's word, and knowing that the bible is God's word depends on the bible saying so. That argument will never conclude, yours will.

This is NOT circular reasoning. Circular reasoning requires that the basis of the argument depend on the the truth of the matter in question, that being evolutionary science s right because evolutionary science said so. The chain of thought is: how do i know evolutionary science is right?? ---> because it said so in the book. ---> how do i know the book is right? ---> because it was written by an evolutionary scientist. The next logical thought would be: How do i know the evolutionary scientist is right?
