Science cannot prove that we are here by either chance or design, but the scientific evidence can be used to support one or the other.
It is only fair that evidence supporting intelligent design be presented to students alongside of evolutionary theory. No one is being forced to believe in God so there's no real violation of separation of church and state.
But, when all the evidence is presented it should show beyond all reasonable doubt that life didn't originate by chance but by design.
The Institute for Creation Research (www.icr.org) offers excellent articles, books, and resources from Master's or Ph.D degreed scientists showing how true science supports creation.
