What is painfully obvious is like, most religous people, you pick and choose what part of Science you want to believe. Saying "proving evoltion beoyond a doubt" is absurd. I can roll out "scientists" who still say that smoking has no correlation to cancer, and plenty of them. You can let people watch the rocket blast off, take a live feed from space, have amatures all over the globe follow the rocket to the moon, and watch live as they walk on it, and there are still people that say it didn't happen.
To say there is no evidence for evolution is inacurate. Many links that show evolution in action have been posted on this site, and ignored by the Creationists. 99% of the biologists on earth (who dedicate their life's work to this topic) do not dispute the overall theme. You can watch it in action with fast multiplying species such as bacteria or fruit flies.
The problem is because of religious zealots all over, most Creationists think that evolution cannot exist with their world view. The more englighted ones realize that the Bible as a guide for their life, not literally dictating history.
