Query: Not as cross-disciplinary as suggested in the text

The book is interesting and suggests extraterrestrial intelligence at work way beyond rational and scientific findings. I don't believe a reach into the scientific through biblical and ancient texts is as convincing as Sitchin would want us to believe. I didn't think enough cross-disciplinary research was looked at in support of the conclusions about human origins and planetary behaviour. I think Graham Hancock's theory about ancient civilization is more convincing than Sitchin's although Sitchin is more entertaining and not as arrogant as Hancock.
