Scientists have been teaching you and I for many decades now, that the earth,the universe, and life are all here by accident. They have a set of theories as to how that happened.
First, an explosion of extremely hot and dense matter took place about 13.7 billion years ago. That explosion sent things out great distances, cooled the matter, and eventually took the configuration that we experience today. This theory has been coined as "Big Bang."
Once the hunk of rock we live on fell into the orbit around our star (the sun), the right conditions came into place which spontaneously generated amino-acids...the building blocks of life. Those building blocks, over time, joined together to form the simplest of single-cell organisms, then more complex, and so on until we have all the life forms we have today. This process of moving from no life, to life, to more complex forms of life is known as "Evolution."
In the scientific community, the combination of "Big Bang" and "Evolution" provide the most accepted and tested theories of the origin of the universe and life. Notice that "Big Bang" does not give us the way matter came into existence. It simply tries to explain how the universe reached the state that it is today. Evolution, however, does attempt to explain the origin of life.
Going back to my earlier posts, then, we have two competing theories for the origin of the universe and life.
- The first theory says that God has existed forever. Then, "God created the heavens and the earth" ex nihilo (out of nothing) and created life. From then on, life has regenerated itself much in the say ways we can observe scientifically today.
- The second theory says that matter has existed forever. Then a great explosion sent this matter all over the universe to create today's configuration. When conditions were favorable, life was formed and then evolved into all the variations of life we experience today.
