wake up call

 everyone on earth came from eight people, Noah, Mrs. Noah, their three sons, their three wives.

The Bible has many examples of God modifying the universe and changing people's brains. First God created everything. 

How could all the differences in people be accounted for by eight people? Easy, God changed people instantly to speak different languages. This required reprogramming their brains, not just with language, but culture and perception. God could easily have changed DNA to produce the different physical characteristics of people.
