I was on a forum I regularly post on recently and a topic came up that got me thinking. The thread was called 'what does it matter?' or something along those lines, and it was asking the question of why does it matter so much to creationists that evolution is false? Unless a creationist answers this question for me I'll still be puzzled, but I can still speculate..
It confuses me because many Christians have already conceded that many of the biblical stories are allegorical or metaphorical, so why not genesis? In fact there is a particular breed of creationists known as old earth creationists, many proponents of the 'Intelligent Design' movement also fall under this category, who believe the Genesis account isn't meant to be taken completely literally, but still reject the fact of common descent.
Their position definitely isn't one supported by evidence, as every single fossil ever uncovered, every strand of DNA, and every living creature support evolution not special creation. Unquestioning faith seems to be the root of this issue, and for some creationists no amount of evidence or reason would ever convince them otherwise. What really irks me about creationism, is that most sophisticated theologians have already accepted the fact of common descent, and have adjusted their theology slightly to accommodate this, but this hasn't trickled down to the rest of the believers.
While I'm on the topic of why does it matter to creationists, I may as well ask myself the same question.
Why does it matter to me that evolution is true?
To put it simply, it doesn't matter to me at all, it's just a matter of fact. It matters as much to me as the fact that the grass is green is. If evolution was proved wrong (This will almost certainly never happen) I would no longer accept it.
