Intelligent designers aka people must also obey the law of thermodynamics,
but unlike life they figured out how to make Aluminium foil, not to mention
Teflon, Polycarbonate lenses, carbon nanotubes and uranium reactors.

Explaining why something is limited does not make it one bit less limited.

All you're saying is biology can make bones but not diamonds. I already
knew that.

> *Diamond is not reactive*

You don't want teeth or a turtle's shell to be chemically reactive you want
them to be hard, diamonds would work great if life knew how to make them,
but it doesn't.

Well all that is real nice. but the entire point of the thing is to
correctly copy information, and the cheapest computer at Sears can
accomplish that task with far fewer errors and do it much faster too. If
life could do half as well Cancer would be virtually unknown.

*> Please. Respect for DNA repair!*

I will give natural DNA repair all the respect it deserves.
