Evolution

Have you ever wondered how this massive universe came into existence? Have you thought to question how and where you are from? Well, most evolutionary scientists believe that the theory of evolution can answer all of these questions. But some of you might ask, “What is the theory of evolution?” Evolution is a theory that the various kinds of plants and animals are descended from other kinds that lived in earlier times and that the differences are due to inherited changes that occurred over many generations (Webster,179).

Most true evolutionists believe that everything was started with the Big Bang about 12 to 20 billion years ago. This Big Bang was an enormous super atom consisting of every piece of matter in the universe. This fantastic fireball sent matter and energy in all directions. After this moment, things began to form and have been getting bigger and a more complex ever since. There is evidence for this extremely hot beginning in fossil form of heat, which can be detected by radio telescopes. Scientists also look at the fossil record to support this theory. They can look at the fossils under ground and see that organisms get less and less complex as you get further and further under the surfac


e. After this outburst, the universe became a cloud of crowded hydrogen. Since there was such a large number of hydrogen atoms and they were so packed together collisions began happening. These collisions between hydrogen soon forced the hydrogen atoms to bond, forming helium. These are the two simplest chemical elements. Nine out of ten atoms were hydrogen and one was helium (Gallant, 12-13).

The theory of evolution was started by Charles Darwin. He first published his book, Origin of Species after going on a long voyage to study the Galapaogos finches (Cambell 432). Although no one can say for sure how or when this great earth came into existence, much of the evidence points toward some type of evolutionary process.

Moving forward about a million years after the Big Bang, the early stages of galaxies started to appear. They basically were loosely packed clouds of helium and hydrogen. These galaxies were shaping, so were the stars. The stars as we all know, come in many different sizes and colors. The larger stars that have been building up for billions of years can produce carbon. Extremely massive stars can produce even heavier elements like oxygen, then silicon, and finally, iron ( Gallant,13-16). After some time past, the Sun was produced and then the planets were formed. Over more and more time, the beau
