The first straight line was not made by a rular because it had to come from nature. So where did it come from?

The better question was how and when a stright line was understood to be straightline.

The reason for this is the history of mankind for the last 10thousand years.\n\nFarming started in the fertile crescent and branched off from there in an east west direction.  For the same crop to be grown at a different lattitude it had to go north and south, at a substantially slower rate, because the plant would have to adjust to the change in sunlight.\n\nTo go east and west from the fertile crescent to france or to china is didn't have to change that much, the plants.\n\nThere were also animals in europe and asia the could be domesticated, like cows and pigs, the animals in africa are zebras or tigers, and can't be domesticated. Modern attempts in other places besides africa haven't proven successful.\n\nSo the farming only hit egypt originally, and maybe spread to ethiopia, but it didn't last to modern times because of the culture of hunter gather that was dominant throughout africa spread and didn't choose to continue farming.\n\nNow the Europeans came in the 1700s and 1800s with guns and germs, and eliminated some of the population and divided the remaining populations,\nyou've seen hutu and tootisy and know that this has to do with an artifical division.\n\n\nSo theres no agricultural base, which is prerequisite to capitalism, which is prerequisite to a nation having wealth.\n\nInstead the continent seems content on the genocidal whims of whoever has the guns left over by the europeans.\n\nGod has nothing to do with it, and anyone who says so, I really question their intelligence.

Adam and Eve were the FIRST people... that did not mean that God could not have created more the same way. Its just a thought:)

It comes from the Prime Mover. The one who started the first large bang. Some people label that first mover as God, Jehovah, or Allah.

Theorytical if the line are formed on a flat gemetrical plane they will not intersect.Or if two tangent in a in the same circle are parallel they will never intersect.\nThe fith postulate of Euclid tackled this question.Later mathematicians, like gauss proved that they could intersect. But this proof was based on a different idea=paralell line having curvatures! Of course they would intersect. So the geometry which based on curvatures was started and was called Non Euclid Geometry.\nActually this could have been proven alot fast with some common sense! In reality it is imposible to construct a perfect circle or a perfect straight line(this is my own postulate).   This is because we are not able to have a perfect resolution of measurement.\nNot matter how you try to measure two parallel line  the results is ether convergence or divergence of the two lines if you make the line long enough!So in practice the 5th postulate of Euclid did have a practical application.

I believe the poetic analogy sought here is "a dream."\n\nHowever, I have no clue why this question appears under "Earth Sciences & Geology."\n\nHope this helps!

The Bible never explicitly says where the Garden of Eden was, but geographic hints in the text suggest somewhere in Southwest Asia (modern-day Iraq).\n\nThis makes sense, since the first cities and the first human civilization started in that region (what the Greeks called Mesopotamia, the region between the Tigris and the Euphrates rivers).\n\nBut, it appears that humans did not originate there.  We only built our first cities there and our first state-level societies originated there.\n\nScientists who study human origins have developed a strong case that modern humans first appeared in Eastern Africa.  Why do they think this?  The fossil record for early humans goes back much farther in Eastern Africa than anywhere else in the world:  In fact, proto-human fossils can be found there that link with the common ancestor we share with Chimpanzees.\n\nAs far as "normal color", please bear in mind that race has very little to do with skin color:  Ethnic variation is more than skin deep:  Anthropologists can tell the difference between a East Asian skull and an African one, or even a Native American tooth from a European one.\n\nSkin color is a superficial difference that has a simple explanation:  The SUN.  Human populations who have lived for thousands of years in regions with intense and direct sunlight have evolved more MELANIN, a sun-absorbing protein, in their skin.  Melanin is like natural sunblock, and it makes your skin darker.\n\nEuropeans are descended from nomadic tribes that wandered in some of the most sunless and desolate places on earth during the last Ice Age.  Without sunlight penetrating the skin, the body cannot create Vitamin D.  Without vitamins or fortified milk to drink, they literally became sick.  Those with lighter skin had an advantage and the population very quickly lost much of the melanin in their bodies:  They lost it in their skin (white skin), their hair (blonde or red hair), and even in their eyes (blue eyes are the result of very little melanin in the iris).\n\nNature has not decreed a "normal" skin color.  Evolution is relentlessly practical:  The best skin color is the one that works best for the local environment.\n\nIn our modern era of sunblock, indoor living, heavy clothing, and vitamin-enriched food, skin color has no meaning except to help indicate where most of your ancestors came from.\n\nA few words about the Bible:  Surgery was performed by human beings THOUSANDS of years before the Bible was written.  We know this because we find skeletons quite often with evidence of dental surgery, skull trepanning (drilling holes in the skull to relieve fluid pressure on the brain), and we also find other kinds of evidence of other surgical procedures.\n\nAs far as "scheduling", just take a look at Stonehenge:  This was built about 10,000 YEARS before the Bible was written and it is essentially a religious ceremonial site that also happens to be an accurate calendar (the ancient Celts were great astronomers and they sighted certain stars by means of those big stones and could therefore predict seasonal changes).\n\nI could go on and on, but I have to end by making a point about the gay thing:  Yes, male and female exist for a reason and that reason has EVERYTHING to do with reproduction.  So, when heterosexuals have sex while using birth control, they are also committing an unnatural act -- according to your logic.  It is also "horrible" for a sterile woman or an infertile man to have sex with anyone.\n\nI think it is clear that YOU are the one "asking questions that will only raise more and still never gets it".

A little over 200 years ago, man thought the world was flat.  Their world had "limits" for them to believe that.  At the time of Noahs flood, their world, the area they knew around them was even a smaller area.  The flood of Noah was just in the area that Noah knew and lived. I'm sure most Christians don't belive in evolution,..so WHY would one make a statement that all the races came from Noah?  Races do NOT evolve. Noah was of a TRIBE of certian people.  Noah was a decendent from Adam.  The name Adam means ruddy complected,..to see blush in the face.  Some need to reread Genesis.  On the sixth day God made both man AND woman.  He gave these peoples to fish and hunt.(the races)...Then on the seventh day God rested,...and THEN He saw He had no man to till the ground. That's when God made Adam,..for the garden.  Then God saw that Adam was alone, so God made from Adams rib a woman especially for him.  Rib means curve,...like in our Helixs curve today;..DNA. Bone of Adams bone, flesh of his flesh.\nThe flood of Noah was in the area that Noah lived,...and it was brought on because of the geber/giants, offspring of the fallen angels.God sent the flood to that area to rid it of the giants.   God shook this earth way before the flood of Noah and way before He made man flesh. Just another thought;...When Noah sent out the dove, the dove brought back an olive leaf.  IF the flood totally destroyed all the earth, then how does a olive tree grow and set forth leaves in such a short time?...  Notice too how many times seven is used?  Seven means Spiritual Perfection.

i really have no idea where it came from. for some reasons monkeys come to mind. i think they were carriers and some human got it and then it just kindof spread from there. it took a while to become mainstream.

Not his original, but the image in the middle of the first link I'm listing is pretty close to Descartes' from De Meteorologica.  The second source has several modern takes on the image as well as a nice physical explanation of what is going on.

In past times, drawing maps was an extremely difficult task: without airplanes, maps were built together by joining many heterogeneous measurements and observations from different explorers, on earth and oceans all around the world. Every map was somehow unique and contained big flaws. If you look at the maps of South America from the years 1500-1600, you will see that there is no west border of Peru, because the Pacific Ocean was still unknown, and other big lands as Australia and Antarctica were absent...!\nAs the explorations increased, the maps improved, but the process was slow.\n\nA quality leap took place with the introduction of aerial photographs. Putting together photographs with a little bit of geometry, you can easily derive precise maps. Still, it requires a lot of work.\n\nNowadays, the entire Earth surface is monitored real-time by orbiting satellites, with an accuracy of a few meters. Starting from these data, image-processing computers can automatically draw maps in 2D or 3D as part of an almost fully automated process. No differences can be found between today's maps, because they rely on the same measurements and there is very little margin to any improvement. So, we can say that today, the Earth mapping and the matching between different maps is a completely solved problem.

It was COUNTROS - Lord of imaginary borders!!!   Actually, countries arose naturally out of the territorial nature of mankind. Individual caves belonged to individual cavemen, separate hills and plains belonged to separate groups of men and women, separate kingdoms controlled separate regions, and so on... Nothing was ever established to begin it all, it was simply accepted because everyone throughout our history divided the lands more and more.   I think that countries should exist, to break governing responsibilities down further than one man to rule all, but countries should never rival each other. Additionally, different countries have generated different civilizations, and with them different values, lifestyles, artforms, and countless different ways to view life itself.

Sand was not invented.  It was created naturally by waves or other force erroding pieces of quartz (a rock) and making it smaller.

I'm going to focus on the usual non-euclidean geometry due to Lobachevsky. In that geometry, there are infinitely many lines parallel to a given line and through a given point. Squares (i.e. figures with 4 equal sides and 4 equal angles) don't have right angles. There is a pentagon with all right angles. The area of a triangle can be determined by the sum of the angles in the triangle (it is proportional to the difference of 180 degrees and the sum of the angles). There is a 'natural' unit of distance obtained from angles between parallel lines and perpendicular lines.

No, it's simple, something can;t come from nothing. It's like pointing to nothing and saying that eventually a monkey is going to appear. They say that we came from a giant piece of matter exploding or a monkey , but where did that come from? They tell you nothing, but something can't come from nothing!
