Fiend God
But then I'm afraid we'd all be good little robots and there would be nothing to learn.
Again, this doesn't follow. I KNOW for a fact my biological parents exist. Yet I'm under no obligation to do anything about it. Knowledge is power, not the reverse.
Why does the rest of the world (nature) not need to know about it? Look at our closest "relatives," the apes? Maybe it's just me, but I can't conceive of them postulating the need for a Creator. They seem to be perfectly content with what nature has given them ... otherwise they probably would have developed their own dialect by now and complaining about it just as much as we do.
So... the fact that less-intelligent species do not speak to you about their existent or non-existent religious beliefs is evidence of God's existence ???
