Oh dear, where do I start?

First, if we are going to play dictionary definition pedant, I can find no dictionary that defines God as the uncaused cause of everything.

Second, you ignored the other sentences of yours that I quoted which make up the argument to which I was responding. That first sentence is just part of what I was responding to. In case it has slipped your mind, the entirety is “Being the uncaused cause of everything is the very definition of God. You don’t need to explain it, because no explanation is possible. It’s exactly what drives materialists crazy.”. So the gist of what I was responding to is really the sentences of yours that you conveniently ignored, although the first is a premise to your argument.

Third, you could replace the word “arguments” in my response with the word “definition” and you haven’t answered that.

Finally, the fact that your response is not on the supposed facts of your case but on my use of words shows that you are talking bollocks.

PS, for anyone else reading this, sorry if I appear condescending, it is difficult not to when you have to explain basics to people who should understand.
