"why is it wrong for Christian parents to tell their kids what they believe is true, but not for a teacher to tell us that we are merely chance accidents that just happened to evolve from the slime over eons of time."

Because it's NOT a question of BELIEF - you ignorant oaf!

"Not only is that unproven philosophical assertion , ..."

First, is it even possible to 'prove' a philosophical assertion?

Second, do the Theory of Evolution and evolutionary biology involve philosophical assertions? Probably only in the minds of creationists.

Third, where's the proof that God created everything? Surely, if you creationists demand proof from scientists then you should be able to provide it for your own "philosophical assertions". But then, God is 'unknowable', isn't He, Pete? So, if He's unknowable, you'll never know if He created everything or not, will you?
