I too have read the free chapters of this book that are available and as a Scientist I find them completely unfounded.
They are written in such a way as to fool people who may not be as clued up on the intracacies of certain scientific fields into thinking that god must exist, regardless of your religious viewpoint this is deliberately deceptive.
It also relies very heavily on the God of Gaps arguement, which in a nutshell is "if it cant be scientifically proven, it must be God", I'll leave you draw your own conclusions to that.
I must point out that on a review of another product, the Aliases "Reviewer" & "C Sheridan" are proved to be the Author himself, so both the 5 star reviews are by the person who actually wrote this book, so I would ignore.
There are many good books on the potential existance of (or not) of God, this is NOT one of them.
