"If you had read it all, you would have seen that our author found numerous consistencies with pagan and atheist agendas and documented them."
Paganism is not atheisism as far as I know. From what I see the book is a hodgepodge of non-scientific nonsense - that is its problem. The teacher and the author of the book may well be atheists but I don't think this sort of irrational, non-scientific thinking is limited only to that group. Indeed, there is plenty of non-scientific nonsensical thinking to be found among religious people too. I bet a lot of Christians would love to see a Christian science textbook which quoted verses from the Bible, etc.
I'd settle for a simple acknowledgement that if all things tend toward an inert state of uniformity (2nd law of thermo: entropy), then complexity has to be imposed by outside force. We haven't "evolved" into complex beings, we were created as complex beings by a "higher power" who has a purpose for His creation.
We don't have to get into the romantic and symbolic language of the Bible to simply give God the credit (and honor) He deserves.
P.S. There are science textbooks with Christian theology that do a very good job on the subject.
