Facts:
- A generation = 25 years (using the highest number in lieu of 20, the number of years for earlier generations)
- 240 = 1,099,511,627,776
- 40 X 25 = 1,000
Given the above, a thousand years ago I had over a trillion grandparents. Correct?
Question: What was the population of the Earth a thousand years ago? Was it over a trillion?
This is an interesting dilema and thought process. But I doubt the populations ever grew at that rate.
Think about tribes. They would probably roughly grow to about double or triple in size before probably being annialated by another tribe (At least thats what I beleive happened here in Africa.. )
