First of all I'm a new guy here I just am just happening by, but this post intrigued me and infact I read nearly all of it. So I had to register and post (as well as another post in another thread).
I'm a YEC but since I can see how the majority of the people here are not really interested in learning and just interested in debating, I'm not going to really bother wasting time saying much. But I will say this much:
Yes every person has a bias, as some person mentioned, we (YEC's) do tend to start from position that the Bible is 100% true and inspired of God no matter what science may say at the present time, because science is fallible and there are only a handful of things we know for sure will never change (gravity, time, round earth, etc) And thus we do tend to try to develop theories to support it. However, do not misinterpret what I mean by this.
What I mean is this. Let's see how I can explain this well and clearly... we still take the facts that are definately there, for anyone to see, creationist or not.
Then we look at the Bible, and take into consideration certain verses which may hint at scientific laws. I'll take a pretty good example here of several verses that explains a current scientific model that is against many evolutionist models, because some evolutionists believe the universe is infinate for instance, but the following model I present (as an EDIT note, I should say that this model is not my own original model, but I've read several new Christian models and this is one of my favorite ones, I could go into more detail into why it's important but I won't here) is provable should we ever manage to explore the universe far enough (so, I'm offering something scientific here, whereas simply saying something infinate is vague and really unprovable.)
Psalm 147:4
"He determines [counts] the number of the stars and calls them each by name."
In other words, I believe this is saying that the universe is FINITE and as a result the number of stars and galaxies are also FINITE. The universe is still extremely large, and we may, in fact, probably will never, map it out entirely.
If God actually counts (ie, he knows the number of) stars, then they must be finite. If the author of Psalms did not want to imply that God made a finite universe, he would have used a different wording. There are other clues (from the Bible) that lead me to believe in a finite universe.
Genesis 13:16
"I will make your offspring like the dust of the earth, so that if anyone could count the dust, then your offspring could be counted."
Now this may seem somewhat unrelated, but I wanted another example of the word "count" used in the Bible in context. Again, we can see that the number of objects counted is extremely massive, yet, it is FINITE, not INFINITE.
Genesis 15:5
"He took him [Abraham] outside and said, "Look up at the heavens and count the stars - if indeed you can count them." Then he said to him, "So shall your offspring be."
Again, God is saying that Abraham's descendants would be very very large, and uncountable by conventional means, but by no means infinate. I mean, there are only a few billion people on earth, certaintly not uncountable, but not really countable one by one by hand.
I'm going to quote one last verse for good measure, and this ties in with the other two I used from the Bible as well:
Genesis 22:17
"I will surely bless you and make your descendants as numerous as the stars in the sky and as the sand in the seashore. Your descendants will take possession of the cities of their enemies.
For those of us who believe in YEC, there will never be a scientific theory or history record that becomes hard 100% fact which can possibly fully disprove anything in the Bible, for if even one event was disproved, then the Bible is actually nearly entirely false and as a result, Christianity would be false.
However. Evolution does the same thing, infact, you could go so far as to call evolution a religion too (that's something to discuss another time and another place though.) I'd say that most people who believe in evolution are also starting from the viewpoint that evolution is inherently 100% accurate, but that some of the scientific models are inaccurate. For instance, the age of the universe and how certain things came to be via evolution are always being modified with scientific theory. But all the evolutionists still believe that all the animals and people etc came about by evolution in some way. I think any honest evolutionist will attest to this.
So basically, we YEC's must keep our foundation (the Bible) as our starting place, and use science to support it. Otherwise we'd be compromising ourselves, since evolutionists also have their own foundation that they work upon.
To say that you don't have a bias, quite frankly, you wouldn't be telling the entire truth. This is the reason YEC's must bring up the Bible even if they are PH.D scientists/engineers/whatever (I'm only on my second year of college myself, but gaining a PH.D is indeed an eventual goal for me).
