Intelligent Design doesn't offer theories on how, but speculates about who. In a general sense, such conjecture is compatible with a kind of theistic evolution, a metaphysical philosophy which I actually find reasonable.
Evolution, embryology and the Big Bang theory are "lies straight from the pit of hell." They are not scientific theories supported by mountains of evidence, as scientists would have us believe. They are a part of Satan's plan to keep people "from understanding that they need a savior."
If evolution is right about how humans came to be, then the biblical story of Adam and Eve isn't. If you believe, as evangelicals do, that God himself is responsible for what's in the Bible, you have a problem on your hands.
As someone raised evangelical, I realize anti-evolutionists believe they are defending the Christian tradition. But as a seminary graduate now training to be a medical scientist, I can say that, in reality, they've abandoned it.
It is a sad day indeed when a faculty member of one of the leading Christian colleges in the nation is threatened with the sack by his president for trying to stay true to the faith of his parents and to the demands of reason and evidence.
