I think that both should be taught because they are the only two ways that people think we got here.
If you are going to defince 'Creationism' this broadly then it is going to be impossible to teache, you will either need a course covering every creation mythology or you will just need 5 minutes to say, 'oh, some people believe that the Earth and living beings were created by some divine being or beings', and that will be it.
It just shows there is a creator and everyone can make that choice WHO that creator is or if he doesnt even believe in one.
Except it doesn't
show it, it just claims it.
It would be bias to only teach creationism or evolutionism alone.
Except that it is an apples and oranges situation. If there were an equality of quantity and quality of evidence supporting the 2 positions you might be right, as it is you aren't.
Welcome to the board by the way.
