We can not justify evolution by saying that it is the best theory. If there were two forms of government, dictatorships and anarchies, which one would be the best? Regardless of which one you choose, they're both horrible.
But wouldn't one of the two be better by someones judgement? This is a false analogy anyway. There are more than two types of governmetn and we know it. On the other hand, there is only one scientifically viable theory regarding origins.
This demonstrates the problem of accepting evolution because it is the best theory. So we must instead compare evolution to the objective truth in our society. Once that is established, then we can work from there to further analyze the role of faith in evolution.
Ah then you are talking 'evidence.' Very good. Please supply us with your evidence.
On a general note, I have a sense that some of you are waiting for me to lay out the tenets of ID so that you can rip them apart. But that is not why I came here. I came here to diagnose what role faith plays in evolution. If you keep that in mind, perhaps my arguments would be more comprehensible.
By your definition of faith, the belief that my truck will start up tomorrow is based solely on faith. You, along with many other YECs, have completely corrupted the definition of 'faith'.
