Over millions of years, there have been many disputes over the true origins of the world we live in. For most Christians, it is sufficient to follow the words from the Bible's Old Testament; more specifically, Genesis. It states that God created the earth and man in seven days. However, others choose to solely follow the idea that first came from the Belgian priest, Georges Lemaitre -- that the universe began with the explosion of a primeval atom: this is known as the "Big Bang" theory. As long as the universe exists, the world's population will continue to question which belief is true or if both can be reconciled and accepted as knowledge, instead of one over the other, or neither at all. It all comes down to this: all we consider to be true are only theories and beliefs; we won't all think the same so it's impossible to prove that both ideas can be accepted as knowledge.
Genesis says that the heavens and the universe were created in 7 days, along with mankind, plants and trees, and animals. He saw that it was all good and expounded each day until he finally rested and felt that he had finished his creation. Christians will say, "What other way could there be? How could things exist without this almighty creator?" .
St. Augustine's book, Confessions, is filled with skepticisms from his own accounts and from what he questions to be true. However, instead of asking, "God, are you real? Did you truly make the heavens and the earth?" he willingly agrees with God creating the world. ("Both the fact of its life and the fact of its living in a blessed stated it owed only to your grace" p.275). It would be wrong, as a Christian, to go against the written word. The church tells us to simply believe and hold the Bible to be truth. It is not our job to object what we are taught by our religion so how can we bring other theories into debate, such as the "Big Bang" theory? So basically, we are expected to believe that that one individual creator used His phenomenal power to bring into existence the universe we live in.
