I mean to say he is the Creator of the Universe isn`t he ? so why would he use such a method that is subject to crumbling over time ?
I remember a JW talk/mag. that said Jehovah was the ultimate chemist after all he created the universe putting all that dynamic energy into an Atom and he could only come up with writing the ten commandments on two tablets of stone ?
Surely he could have used something that would not disintergrate so easily over time ,some alloy or such that humans have perfected till now.
Obviously he wasn`t thinking very far in advance
