@RandomGirl One cannot “just point out” something disputed. We happen to disagree about the history of mankind. Even if your claim about history were true, however, it would be irrelevant. The crux of my point is that we do not need marriage in order to get children. I assume you would agree with that, yes?
Moving on, then, I would like to make a few points about this post. The first is that you commit a very basic false dilemma fallacy. There are more choices than “nothingness randomly exploded” (which no one believes, as yours is a straw man version of one possible atheistic cosmogeny) and a particularly Abrahamic version of theism. It seems there is quite a bit more research for you to do before you can make an informed decision.
Second, believing in God—or even in a creator God—does not immediately entail that the Bible is both accurate and literally true. For one thing, there are theistic religions other than Christianity. For another, Christianity (and the Bible) could be true without being literally true. One early proponent of this view might be familiar to you: Jesus of Nazareth, who spoke in parables that must be interpreted. If you take them literally, you will miss the point.
Third, I fear you may be equivocating on the word “proof.” Science operates on the epistemological notion of fallibilism, which is to say that it never rules out the possibility that future information may overturn current theory. That is not to say that science cannot prove anything, however, unless we have an overly robust notion of “proof” under which only 100% certainty counts. I am not 100% certain that I am not a figment of Cthulhu’s dark imagination, but no reasonable person would think that meeting me in person was not adequate proof that I exist.
Fourth, the “evolution is just a theory” gambit just doesn’t work. For one thing, it confuses the scientific usage of the word theory with the colloquial usage thereof. In the scientific sense, a theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. It is not a guess, a prediction, or a supposition. A scientific theory collects a set of facts together and explains them. Evolution is a theory in this sense, and it is one of the best confirmed theories we have.
