First, all scientific reason that I have is based on faith. Theories are nothing more than models of reality. Anybody who partakes in science is putting faith that these theories are reasonable representations of reality, but that doesn't mean that those representations are reality, nor should it be taken the other way; they could very well be how things work. Therefore, everything that I state is based off of faith, even through science.
The difference between science and faith is that if reality does not uphold your science then the theory is changed or discarded. Some examples:
Newtonian Theories were upheld for a long time; however, because of their failure in predicting the orbit of Mercury they were found to be wanting. Einstein changed Newton's Laws into the Theory of Relativity.
Atoms were once thought indivisible. Then we discovered electrons, so atoms were thought to be electrons in a "Plum Pudding." Then Bohr discovered the nucleus and thought that electrons orbited the nucleus of an atom like a little planet. Now, because of advances in science, we know that electrons exist as a field of probability around an atom in certain locations. Until we find that this theory does not sufficiently explain reality, which I fully expect to happen.
On the other hand. If I state that there is scientific evidence to prove that the earth has been around longer than 10,000 years, a young earth cult will dismiss that and affirm their theory of god without evidence.
Religion is a theory which must be upheld despite evidence.
Science is a theory which is only upheld because of evidence.
Plus, I mistyped what I had really meant. I believe in God, and I believe that God created the world and universe in seven days. Nonetheless, I have several theories as to how human existence could come into play (happen) - even without God - and only a couple theories as to how the universe could be created - once again, even without God - and I have only two (maybe could be three if I were to think hard enough) ideas as to how the matter came into existence.
I would be interested to hear these theories. But this begs the question: If you can conceptualize how everything can exist independent of god, why do you believe in god?
Why I put that was what I believed is because I know that God could do it anyway he wanted to, but he did it in a way that wouldn't be lying (meaning he wasn't using a metaphor when he said 7 days), with the earth and universe being 10,000 years old, and the universe having a multi-billion year old history, according to the Bible (which I also have put faith towards being accurate). But, that isn't the only way I believe God could have created the earth in seven days, I have more ideas to as how he could have done it.
Here's the problem with the Bible though. It is a very human document written with very specific political reasons in mind.
Here's a short example of the cultural and historical underpinnings of the bible that you undoubtedly did not know about. If you would like to find out more, I suggest starting with "A History of God" by Karen Armstrong.
The creation story from Genesis 2 on was written at about 1000BC and it is based off of the Enûma Eliš. However, Genesis 1 was written at about 600BC to replace the god Marduk slaying the Dragon Tiamat, who was the embodiment of Chaos, and then out of her body making the world, the firmament, dry land and people. This act was attributed to Yahweh, and is mentioned in the later chapters of Isiah (which were written by the same person. Yahweh slaying Leviathan.) This is why animals are created twice, in Genesis 1:24 and Genesis 2:19. It's quite literally two different stories that were written 400 years from each other.
In fact Yahweh is a Canaan god. And all Israelites that you have read about in the Torah and early bible, Abraham, Isaac, Moses, were all polytheists just like their polytheist contemporaries. For instance Abraham worshipped El Shaddai or God of the Mountain, which is another name of the Canaan god El Elyon. Abraham and Jacob make El Shaddai their elohim or primary god. This was something that Canaanites did to gain special favor from a god. Its usage does not make sense when there is only one god.
Note please that El Shaddai and Yahweh actually are different gods. Yahweh does not enter the story until Exodus. Yahweh is the god of war. This is why he was so bloody in the old Testament, he's pretty much the equivalent of the Greek God Aries.
This is not just supposition and speculation, we actually have archaeological evidence from 1000BC in the form of cult stands that shows that the Israelites primarily worshiped the Canaan gods El Elyon, Yahweh, Baal, and Asherah.
So in conclusion, please be aware and wary of what you read in the bible. There is much more to it than what is on the surface.
