Since “both sides” means the scientific side and the religious side, only one gets to be taught in science classes and the other may be taught in elective religion classes.
I think that's false.
One side says -- look at this neat evidence! This evidence makes us think that random mutation and natural selection is responsible for speciation!
The other side says -- look at the complexity! The complexity and inter-relatedness of natural systems makes us think that random mutation can't be responsible!
Debate the differences. That's science. Swallowing one half of the story -- that's religion!
Both sides are religious. One worships blind chance.
