Is it scientifically possible that a thing can build something more intelligent than itself? The answer is a big NO.
The only reason why human DNA can transform into a more intelligent human BRAIN is because the transfomation is guided by someone more intelligent. Nothing can create something more intelligent than itself and that's a fact.
There MUST be a MAKER in between. That is science and most of all, that is COMMON SENSE.
Those who say there is no Creator are fools and devoid of common sense.
