Anybody have any idea how many people have lived since the creation of the world?

If they were all alive and in one place, how big would the place need to be?

IIRC, more people live right now than all the people that ever lived before.

Yes, but nowhere near 51%. Or the 75% listed as a claim in the article.

My immediate thought about this was "where do you start"? Where do you put down a finger and say "humans started then"?

I think their number is probably a bit low because of that, but it's still amazing to think that so many people live on the earth now that it's actually around a full 5% of the people ever.

Imagine if every person who ever lived was gathered together. What a crowd that would be!

Xavier -- that was a cool link! I liked reading that.

So that center estimates 106 BILLION people? Wow! That is a mind-boggling number.

Now Katarin's second question -- how big of a spcae would be needed if they were all alive at one time? How do we figure the space-per-person needed?

When I was a girl in Hebrew School, the Rabbi told us that in the time of Moshiach (Messiah), all the dead people would be resurrected. So I asked my Rabbi how the world would be able to fit so many people -- it seemed that we couldn't fit the ones we have already.

He said that it would not be a problem. Cemetaries would no longer be needed, so we could build high rise apartments on the cemetary grounds to hold all the resurrected.

Neat, huh?

I wonder what all those resurrected people will think of high rise apartments... and the internet!

I need at least 18 inches of personal space around my person...but I'd rather have 24..

If everyone was ressurrected, most would be babies and kids. Sad.
Unless there's an arbitrary cut-off age, like in Phillip Jose Farmer's Riverworld series. I believe he estimated about 38 billion adults (over age 5). So recent humans would make up a larger proportion of adults than 5% among total past popualtion. Perhaps 10%?
quote:
Life expectancy at birth probably averaged only about 10 years for most of human history.
...
Infant mortality in the human race's earliest days is thought to have been very high — perhaps 500 infant deaths per 1,000 births, or even higher.

Wow, I knew infant mortality used to be high, but 50% or more??

That's also the thing that confuses people about the average life expectancy in the middle ages and the like. The main reason its lower is because infant mortality was far higher. It doesn't mean that it was all that hard to find a 70 year old man.

Edit: Doing a google search to substantiate this claim, I found a like that says Angola has 192.5 deaths per thousand infants and a life expectancy of 36.8 years. That fits about what I've heard about the middle ages' stats.

Considering that a modern country has a 19% infant mortality rate, I'm not surprised that it was over 50% at some point in our species' past.

Actually, that brings up an interesting statistical exercise. The probability that something will happen is the number of times it happens, divided by the number of trials made. So if 95% of all people who have ever lived, are dead, that means you have only a 95% chance of dying, statistically speaking.

KoM, that was the most amusingly bad abuse of statistics I have ever seen.

Think again about what would constitute a random sample from the overall distribution to see why your attempt at statistical analysis is silly.

For Tante Shvester,
Most likely, no one will be ressurected.
The def of ressurected would imply that the deceased gain new flesh.
That will only happen if Hell is on earth where people are as they were before they die.
The Bible says that the deceased believers in Jesus will assend into heavon, but have a new spirit.
So, therefore mostlikely "no onewil be ressurected.
You may believe that if you want, I take no part. I only present info as i know it and am glad to be proven wrong.

Well, since Tante Shvester doesn't believe in that part of the bible, she is unlikely to find your cite very convincing.

That stuff that happens including and after Jesus, they don't believe in. If they did believe in it, they would be called Christians.

We don't. (I say we because I am Jewish as well.)

We keep the original text, and ignore that which was added later -- and which contradicts large chunks of the original.

That which you call "the New Testament" is of no interest to us.

*whispers* Dude. Are you unaware that the Old Testament is called the Old Testament by Christians because it came first? Before, in other words, the New Testament -- the bit with Jesus in it -- was written?

Eyetell,

Yeah, what rivka said. For the Jews, the Bible (what we call "Torah") is true and given to us directly from G'd. Up to a certain point, where it ends. This is what Christians call the "Old Testament" Everything after that, we do not accept as G'd given gospel.

So, it's not exactly like I faithfully serve one part and throw out the rest. It is more like I faithfully serve the whole thing, and nothing further.

Of course, this is the Jewish perspective. I mean no disrespect to those who accept as Word of G'd that which came after the Torah. So, if the New Testament, Koran, Book of Mormon is holy to you, I respect your beliefs.

And as to the truth about any life after death, I am willing to postpone knowing it until later. It is not a cornerstone of the Jewish faith.

Dude, I said this once already, so try listening this time. There's only room for one religious troll on these here boards, and the position is already taken. Shape up or move on.

Incidentally, remind me never to be in the same room as eyetell. We would probably both annihilate in a flash of radioactivity, or something.

I heard (no sources on this, sorry) an estimate based on the Christian start of man; or in other words: about when Adam is thought to have lived. It was around 30, to 32 billion.

If you don't mind, could you please spell 'atheist' tight? 'Athiest' sounds like a superlative. "I'm athier than you are! I'm the athiest man in this room!"

And according to my terrible calculations, each person if alive today would get 0.0013963185411527606983695309909532 square kilometres of land each. Which is a little over a metre each. 1.396 sq metres.

However, that is counting land only. If the sea was open for colonisation...

0.0047913150821181997509169589324475, which is nearly five square metres EACH! WOW! That's space to lie down on! Space to pace in! [Big Grin]
