To the nearest billion? 0.1 billion? 0.01 billion?

There are censuses and estimations of course, but they can't possibly count everyone.

What about people who live in undiscovered tribes?

What about people in very rarely visited nearly pristine tribes? Do they send someone out to bother them for the first time in years just to check how many there are?

Do estimations include take this into account or not?

There can't be too many of them, all the people living in 3000 B.C. for example was ~0.1 billion, and that was when many had already found farming.

What happens when there is a war or drought like the Rwandan genocide, they can't keep track of how many people die.

What about illegal immigrants, the homeless, the really poor, people without a permanent place of living, people who are less likely to be counted in a census.

Does the world pop estimate include them?

Why does the universe seem so fine-tuned for the emergence of life, including intelligent life capable of asking that "why" question? Believers say that God did it, while evolutionists and science are trying to come up with complicated extradimensional multiverse theories to explain our lucky break. The laws of physics just happen to permit life, is no explanation. The attitude of even the most intelligent human being toward God sees the universe marvelously aqrranged and obeying certain laws but only dimly understand these laws. I'm not trying to change your views here, I'm just posting a question for you to put forth an answer whatever it might be.

could they have been informed of the end of the world in 2012, by a third party such as aliens, they may have told them it ends at 2012, or maybe, the aliens are going to Come back at 2012?? What do you all think about this?

I think that if we plan on ever doing long space trips, we will need to have an artificial gravity.

If the universe was to be a shape, wouldn't it make the most sense that it was round? Everything in the universe seems to be Round, the atoms are round the planets are round, they spin around, the galaxies spin around, it's all circular like motions, even the atoms move around in a circular motion. wouldn't it be odd if the universe itself was circling around a bunch of other things? maybe something Huge we don't even know about?

if so why is the earth thriving with life and the moon so dead? since both these bodies are so greatly close to one another on the cosmic scale and the sun make life possible on earth why not the moon too?

I am very curious about black holes, ever since I was told that a teaspoon full of the material from the average black hole weights more then mount-everest. I would love to learn all I can about them, and thanks SO much for your help.

I was wondering why mars' gravity is only 38% of ours...
I thought gravity had something to do with it;s speed of rotation- but it's day is almost the same length as ours...
Please help!

Also when it says that mars has some spots of magnetism left from an old planetary system, what does that mean, and how did that happen?

So confused!!!!
