The reason intelligent design was never considered is becuase courts refused to hear the case about it because, oh no, it could mean that there is a God!
Sorry but that is simply incorrect. Not only have there been many court cases related to ID, in almost all the main opposition to ID or Biblical Creationism has been from Christian groups.
Every single major Christian church accepts teaching Evolution and opposes teaching ID or Biblical Cretionism.
In the most recent court case, the one in Dover, the ID and Biblical creationist supporter got beat so soundly it was funny. For the first time it was placed in the legal record that the proponents of ID want to define science so broadly that palm reading, phrenology and astrology would qualify as science, and that the proponents of ID and Biblical Creationism lied directly and repeatedly under oath.
