The definition of religion intended by the constitutional ammendment requiring separation of church and state is definition 1, "Belief in and reverence for a supernatural power..."
While one can pursue an activity with the religious zeal of definition 3, that doesn't make it the object of worship of definition 1.
Because it is based upon the account of creation from Genesis 1 and 2 in the Christian bible, Creationism is religion. And because evolution is based upon evidence gathered from the natural world it is science.
