Its good that you keep your faith flexible enough to work with science.
I would also question the validity of that study. The human genome was done in 2003 and the Chimp one had a rough draft that same year. If you cant tell us anything about this? Where did you see the documentary? In what month? On what channel/program? Who narrated it? Who did it feature? Was this study published and if so where? Any of this would be helpful.
