Query: Amateurish -to say the least

This is a very superficial book -to use an understatement.No references are given , except for citation from the Bible.One cannot verify the author's statements/interpretations.By the title it seems to me that the author looked for ( and got) the attention of potential buyers , attracted by the spectacular title.Scientifically (and otherwise) the value of this book is exactely zero.Do not buy it.
