Critics ask, if it's true, why don't they teach it in schools?
The reason it's not taught has nothing to do with truth, but rather law.
You see, evolution theory is the only theory in all of science that is protected by law.
Top that with the fact that everyone who wants to get an alternative to evolution taught side by side in schools is met with heavy attack, ridicule, and threats.
Ask yourself, why would an atheistic group attack something that is scientifically accurate while at the same time saying it doesn't matter and it's not a threat?
The legal staff of Freedom From Religion Foundation, a church-state watchdog group, has had remarkable success in convincing many institutions such as school boards and town councils that they are breaking constitutional law when they sponsor sectarian activities.
That includes intelligent design.
When the authorities can't be convinced, Freedom From Religion Foundation sues, and it wins more often than not.
