The best part I think is that there exists the possibility for creationism and evolution to coexist. Just because we know we evolved doesn't dismiss the potential liklihood that we did so to a grand design. Our current species could be simply the final version of a cumulative project. "God" a disenfranchised Genetic Engineer failed dozens of times in taking a foreign cell structure and making it into his image, until one day he succeeded in tweaking genetics to the point that "WE" blinked into existence. Hell for all we know Neanderthals were just a failed genetic concept that should have stayed on the drawing board in the heavens. Perhaps Satan got tired of Gods sh*tting up natural processes and decided to go rouge and protect a singular species from further genetic modification, maybe we are rooting for the wrong guy?
I don't know about a 'grand design', but I do agree that there's room for both. The amazing thing about belief in the major religions is that you can replace the word "angels" with the word "aliens" and suddenly, the stories make sense as interpretations of things humans didn't have the language to explain when the texts were written.
Were we ooze? Probably. Why are there still apes? A subset of apes, perhaps the most advanced ones on the planet when "God" arrived here were altered in some way and set on a different path. Those non-coding sequences someone mentioned? Some of it isn't seen in anything else on the entire planet.
This path of study is fascinating because we are an entire race with a really bad case of amnesia. *Something* happened, but we don't know what it was. We've had influence and help from *someone*, but we don't know who it is.
I say teach both in schools, but in their respective places. We're eventually going to find the link between the two, and we do need to keep what little memory of our history we do
