Oh, I have plenty of biases, all right. I’m quite biased toward depending upon what my senses and my intellect tell me about the world around me, and I’m quite biased against invoking mysterious mythical beings that other people want to claim exist but which they can offer no evidence for.
By telling students that the beliefs of a superstitious tribe thousands of years ago should be treated on an equal basis with the evidence collected with our most advanced equipment today is to completely undermine the entire process of scientific inquiry.
And one more thing: In your original message you identified yourself as an elementary school teacher. If you are going to insist on holding to a creationist viewpoint, then please stay away from my children. I want my kids to learn about “real” science, and how the “real” world operates, and not be fed the mythical goings-on in the fantasy-land of creationism.
