Gah. For centuries we have been filling the gaps in scientific knowledge with the concept of "god".
At one point no one could understand how the sun rose, so a "sun god" made it rise. Now we know about gravity, centripetal forces, etc...
We didn't understand how crops grew. So we made sacrifice to various gods to make them grow. Now we know about photosynthesis, nutrient osmosis, etc...
We couldn't understand mental illness or brain damage. So we drilled holes in people's skulls to release the evil spirits. Now we know about brain tumours, schizophrenia, etc...
And now. Well now we understand a lot of what goes on in the world. But we still can't conclusively prove how we got here. So it must have been god. Or intelligent design. These so-called scientists are putting forward a "theory" that is so riddled with holes it's ridiculous. Saying "it must have been a god" is not a theory. Sure evolution is not perfect, but we can back it up with a good couple of hundred thousand pages of evidence, and many, many supporting archaeological finds.
The "evidence" for intelligent design is merely the gaps in the evidence for evolution.
Give me good, hard scientific evidence for the existence of an over-seeing diety, and I'll accept that it should be taught in schools. Otherwise, keep it in church.
By the way, the evidence is not a 2000 year old book (though it's not 2000 years old, it was written a while after the actual events). And pointing at stuff and saying "it's so wonderful, it can't have been by accident" just doesn't cut the mustard. Exidence is tangible, i can touch it, examine it, carbon date it.
