I did not claim god cannot exist because evil exists. That would be as silly as it is to interpret my remarks that way. What I claimed was that any god that coexists with evil is irrelevant from a practical standpoint.
I appologize for having misread you.
Having said that:
"What I claimed was that any god that coexists with evil is irrelevant from a practical standpoint"
Why would that make any deity irrelevant? That's like sayign "A man without property is irrelevant because he allows a man with property to exist"
It's a matter of free will again. The relevance is we as Man have the choice to follow the master we want.
