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.. )
I chose 25 years as a working figure to illustrate my stance, but will gladly recalculate using any number of years between generation up to 50 years on average, albeit hell, even 70 years between gens gleaned from the KJV would suffice.
