Should schools "teach all sides" regarding scientific theories like plate tectonics or germ theory of disease?
"Because the Evolutionary THEORY is also being taught. Fair game, we can't prove 100% that either one is an absolute. We should be able to hear all sides."
Some people believe (without any evidence) that diseases are caused by sin, or by black magic. Should schools teach this, or should they teach the only established scientific theory?
Some people believe (without any evidence) that earthquakes are caused by monsters, homosexuality, or women dressing immodestly. Should schools teach this, or should they teach the only established scientific theory?
If there isn't any evidence for a hypothesis, it doesn't become a scientific theory. Scientific theories are supported by all the evidence.
And as for the age of dinosaur bones: A murder victim's doesn't have a tag giving the name of the murderer, but the evidence often allows us to find the guilty party.
It's a shame you don't understand radioactive decay.
