This matters!

Indeed it does. If you don’t think that teaching evolution matters, consider that medical advances, biotech, and genetics other related industries would not exist but for the understanding of evolution. This is an increasingly important part of the US economy, and undermining the education system diminishes the economic vitality of the nation over the long run.

This has economic effects in the long term. And that matters and will continue to matter.

Much more immediately, once again I repeat with emphasis:

Science belongs in a science classroom.
Religion does not belong in a science classroom.

If you want to teach religion, it belongs in a class on religions, sociology, or other social sciences. It has no place in the science classroom. Creationists may try to couch it in terms of teaching the controversy or that it’s intelligent design or other similar wordings, but scientists have shown evolution exists, it is occurring at present, and that ID and other creationist iterations do not meet the criteria for being considered in a science classroom (like the ability to be tested, repeated, etc.). Religion is based on belief, not facts.
