Ok, so yes, your question was very confusingly worded. Not only is the "exists" and "existed" distinction important, your "would" questions might be clearer as "does". That would make the nature of the question clearer but also make clearer whether there is any point or meaning behind the question in the first place. Obviously if some kind of god exists, it's nature and actions would have to be consistent with what we know and observe to be true. That isn't unique to ideas about gods of course, the same principle applies to any hypothesis.
Yes, if God exists, it's nature and actions would have to be consistent with what we know and observe to be true, and that is what I was trying to get the atheists to think about.
Yes, it would have been clearer if I had asked:
1. If God exists does God communicate directly to everyone?
2. If God exists does God prove that He exists to everyone?
But then it would have been too easy to answer and it would not have accomplished what I wanted to accomplish.
I said
would because I wanted to get the atheists to think about
what God would do if God existed, consistent with what we know and observe to be true in our world. (Of course, God could always do something different in the future, but I was thinking in terms of what has happened to date.)
Such a god could have existed though (after all, anything is possible, especially if you're talking about supernatural beings). You've just shown that kind of god does not exist.
That is correct, so what I was trying to get atheists to realize is that if God exists, God would not communicate directly to everyone or prove that He exists to everyone, not unless God does something different in the future from what He has done to date. But why would God do what He has never done before? That would be like admitting He was wrong and God, if He exists, is infallible, so He cannot make any mistakes.
I'm don't see how this matters though, to atheists specifically or in general. Gods that would make grass pink, create two moons or give humans wings could have existed but clearly don't either, along with a literally infinite number of other hypothetical gods you might care to come up with.
What God would do (or does) would only matter to atheists if they are waiting for God to do something different, like communicating directly to everyone, something that God has never done before. I doubt many atheists are waiting for that to happen but I know one atheist who might be, ludicrous as it sounds. Expecting God to do an about face and suddenly start communicating directly to everyone is just as ludicrous as expecting God to send Jesus from heaven through clouds down to earth, something God has never done before, yet multitudes of Christians believe that is going to happen when Jesus returns.
