That's an argument that a God that could communicate more effectively than that and wants to doesn't exist.
You only imagine that some other kind of communication would be more effective, you do not know that. It is only your personal opinion, not a fact.
We know that if a deity exists, it either cannot communicate directly to human beings or is uninterested in doing so.
That is correct.
And I answered you. I answered your question and more. You seem to object.
The only thing I object to is atheists who say what God
should do, as if that could ever know more than God. With atheists it is always about what God
could do because God is omnipotent but they completely disregard that God is also omniscient so God knows everything, which means that it is logically impossible for them to know more than God since nobody can know more than everything
Who are you to tell the Almighty God, the Creator of the universe, what He should do?
A guy who knows how to communicate effectively. Of course, I don't believe in gods and so don't tell them what they should do. My advice is for anybody that wants to be heard and understood. I would give the same advice to you if you asked me how your words could get to more people. We could add additional discussion sites. You could start a blog or podcast. You might try to get a book published. But I wouldn't advise you to to find a messenger. Do it yourself, as directly as possible. Perhaps an infomercial. I'm sure that deities can do at least that well.
But since you are not God you do not know what would be the most effective kind of communication
for God to employ towards humans in order to accomplish what God wants to accomplish. Moreover you do not know anything about God do you don't know that God could communicate directly to humans and be heard.
You just believe like all atheists that
God is omnipotent so God can do anything. Even if God can do anything that does not mean that humans can do anything and humans cannot understand God directly communicating to them. Moreover, if you heard a voice and it said it was God, how would you know it was God and not an auditory hallucination? You would not know, you could never know that it was really God. Sadly, atheists who believe this way have not really thought this through.
Do you think you can know more than an all-knowing God regarding the *best way* to communicate to humans?
Apparently - if you think that a deity would communicate to man through a human messenger telling people what this deity told him to tell them. Imagine there really were such a deity and it choosing that path. It's not an idea to seriously entertain unless you have to. Baha'is have chosen to believe that happened, and so are compelled to believe that a deity not only would do that, but did. You're not alone. Many other religions have done the same, and also tell us that a deity has communicated to humanity through other people.
It is incredible that you think
you know more than all the religious people know about what God would do if God existed.
You do not believe that God would use Messengers or some other kind of Intermediary because you think that God would speak directly to humans, but there is
no basis for such a belief. You believe that would be more effective, but you do not know that, you just believe that, based upon no evidence whatsoever.
By contrast, what we have evidence of is that God has used Messengers or Prophets throughout human history, and as a result about 93% of people in the world believe in God. The 7% of people who are atheists are outliers and they believe that they are right and all the believers are wrong. That is an untenable belief.
Mind you, I am not saying that God exists is true because most people believe that God exists is true, because that would be the fallacy of ad populum. I am saying that there is a good reason why 93% of people in the world believe that God exists, and it is because God has communicated to them via Messengers or Prophets since the dawn of human history.
