plornive,
Well it seems that you do have faith in evolution. Let me explain...
Simple fact is, 'you weren't there'. When you formulate an opinion about the past you are exhibiting faith in your 'calculations' 'theorys' etc... plain and simple.
Science isn't as exact as they exhibit it to be. There are numerous factors that play into formulating a theory. Firstly, it has to be testable. Secondly it has to be measurable.etc. You don't know how many controls they have to throw out just because it doesn't support their postulation (pre-theories).
There have been numerous debates about the age of the sun, for example.
After all what is belief? When you consider temporal issues like time, since we can't see the future, we have to exhibit faith that things would be consistant. Can I beleive that I will wake up tommorrow morning? Shure, why not. I have been waking up in the past 27 years, it's measured, why not tomorrow? Will I know if I will have massive failure in my vital organs and die? Probably not. I have to have faith in the fact that I WILL wake up.
