Almost everyone on Earth has 4 Grandparents
4x4=16
16x4=64
64x4=256
256x4=1024
1024x4=4096
4096x4=16,384
16,384x4=65,536
65,536x4=262,144
262,144x4=1.04 million
1.04x4=4.16 million
4.16x4=16.64 million
16.64x4=66.56 million
66.56x4=266.24 million
266.24x4=1.06 billion
1.06x4=4.24 billion
4.24x4=16.96 billion
That is 16 generations ago or about the time the American colonies were being formed.......what was the world population then? Surely not 16 Billion?
