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, â€œWhat is the theory of evolution?â€ 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 surface. 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).
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.
