Define 'human'.
Usually, as homo sapien.
As for the rest of your questions, I would have to research it.
Or, 'you' can start with this:
The population of the planet reached seven billion in October last year, according to the United Nations. But what's the figure for all those who have lived before us?
www.bbc.com
I call B.S. on Wendy Baldwin's math.
In reading your link... She states that we surpassed 7 billion dead sometime between
8000 bc and 1 AD and though she doesn't continue on....
that would mean 100 billion people have lived and died in the last 2,020 yrs.
The United Nations, [the same people who brought you global warming?]
Claim 107 billion dead in 50,000 years but deny fluctuating climate heating and cooling cycles haven't occurred in the last 10,000 years until now?
Man doesn't know Jack. Hxll mankind did not even know that the Jet Stream existed until the mid 1940s.
IF scientists are so keen on evolution?
Why haven't they addressed which of the races has evolved the least and which the most?
It's all based on what story they want to sell to the next generation.
From the time of Socrates until the 1930s scientists claimed that the bible was wrong because it stated "In the beginning" and every intelligent scientist knew or had been taught there was no beginning nor end to the universe and that it's existence is and was eternal. Then along came the Big Bang theory shooting their previous knowledge all to hxll by stating there was indeed a beginning.
Even worse, Christians wet their pants and rather than celebrating the bible was being proven correct, they proceeded to soil themselves. Because it didn't fit with there simplistic notions taught by simplistic teachers who never had understanding of what was actually written to start with, nor capable of rightly dividing the word from the teaching traditions of man.
Traditional archeologists date the oldest city ever discovered to about 6,000 years old. 6,000 - 2021 = 3979 bc
hmm that fits within a couple hundred years of what is written.
Now some archeologists believe they have evidence of a city that existed approximately 200,000 years ago. And Christians without understanding will go nuts. As it is written the wisest of mankind's wise men will be confounded, because they ain't 1/2 as smart as they think they are and I'll leave it at that.
Bottom line: I disagree with Wendy Baldwin's math saying 100 billion people have died since 1 AD.
