The Super Summary of World History - Alan Dale Daniel [6]
Here we may note the vastness of the universe. One light year is about six trillion miles, and it takes 100,000 light years to cross the Milky Way—our galaxy. The Milky Way may contain as many as 3 trillion stars (suns). From our sun it would take about 26,000 light years to reach the center of our galaxy. Our sun, which is at the end of one of several arms spiraling out from the center of our galaxy, revolves around the center of the Milky Way about once every 220 million years. The size of the universe is tough to determine, but the observable matter is about 93 billion light years across. Even our solar system is large. Neptune, the most distant planet from the sun in our system, is 2.8 billion miles away. No matter how one slices it the universe is a big place.
As the universe formed our solar system fell into place with its planets circling a medium sized yellow sun. Our earth circles in the diminutive life zone at the perfect distance from our sun. The moon, one of the largest and closest orbiting objects anywhere in the solar system, probably formed after a collision between earth and some other earth-sized planet. As the two planets blasted into one another the moon tore away, and by some means the earth managed to acquire more iron from the striking planet thereby creating an especially large iron core. This outsized iron core produces unusually strong magnetic fields which shield the earth from deadly cosmic rays. Without this large iron core no life would exist on this planet. This scenario is not fact, it is one of several theories trying to explain the uniqueness of our water-covered planet. After everything had formed up and the surface of the earth cooled enough the march to life began . . . somehow. It is extremely hard to say how. No one knows how life first formed or how it came to be so complex so quickly. The theory of evolution tries to explain the development of life after it began; however, it has no application to the question of how life started.
History deals with people and not the physical events described above, but knowing the earth is a rocky planet with water—lots of water—at the exact position in the solar system it needs to be, and with many exceptional features that sustain life, helps us understand the uniqueness of our planet and thus ourselves. Even our universe is exceptional. For life to exist anywhere in the universe several of its most fundamental properties must be present at pinpoint exactness. To illustrate: the relationship between the strong nuclear force and the electromagnetic force[1] could not vary by even one part in 10 to the 16th power (1016), otherwise life would not exist on our planet or anywhere else. Commentators and scientists remark that perhaps the most amazing thing about the universe is that it is understandable. Somehow, mere people—less than a flea speck in the universe—figured out how the universe works. These patterns ordering our universe are dense and intricate beyond all imagination, nevertheless, on both the subatomic and universal level the patterns are there. Because our species discovered these breathtaking patterns we know chaos does not rule our universe or our world. Why our world and the universe are so well ordered on so many levels cannot be explained by science.
Now, on to people, their decisions, and history.
For our purposes, prehistory starts about 150,000 BC when modern man comes onto the scene, and ends about 3,500 BC when writing makes its appearance in Sumeria—according to widely accepted current theories. By definition, history must revolve around the written word. Without the written word history, as we will use the term in this study, does not exist. When we say writings we mean text by someone who lived at or near in time to the events, and who witnessed or participated in the events or at least talked with those who did. In this way we can attempt to reach back into the
