No, it wouldn't. It could be that something political was going on.
Some people don't believe that Neil Armstrong has been to the moon. They think that it was all political and simulated in a studio.
I don't believe that, of course
A voice from the sky would be far more effective than a man on the moon. A voice from the sky would result in the US military sending up F35 jets into the sky for security reasons, all the other countries would do the same and every country in the world doing this would report it to not being a hoax. This event would be covered by ABC, NBC, CBS, Fox News, CNN and every other media outlet worldwide stating it is not a hoax. You would experience the exact same thing the guy next to you are experiencing. A voice from the sky would be 100 times more effective than watching something on TV.
However, if I saw on the News that G-d had "spoken from the sky", I would be highly skeptical. Why would He do that?
Perhaps he would do that because that is the most effective means of getting his message across.
Plenty of people have a strong faith
But if the vast majority of people have faith in the wrong God, are getting the wrong message, or are getting manipulated by crooked people claiming to speak for God. A voice from the sky would clear all of that up; everybody would be able to get their information from the source instead of secondhand information.
WITHOUT G-d shouting at us for no reason as to "force us" to believe.
A voice from the sky would not force anybody to believe, you still have the option to reject the voice from the sky.
Believe what, in any case? That G-d has a voice box, or is able to
make miracles?
Believe you are getting your message from God himself instead of men who write books claiming they speak for God without providing proof that they actually do.
That is already known. By definition, one who is responsible for creating and maintaining this universe can do practically anything.
Evidently he can’t convince most people of who he is because not a single religion has the majority of population as believers. However a voice from the sky could clear all of that up.
That wouldn't include the absurd, because we are not making claims about illogical trick statements.
A voice from the sky is not absurd; after all how many times has a voice from the sky happened in the Old Testament? If it were not absurd then, why would it be now? Especially when such a voice would be confirmed by the technology of today
People who don't accept Jesus or Muhammad have their reasons.
Yes! Jesus never wrote anything down so nobody really knows what Jesus actually said, we just know what other people claimed he said (and of course there is not a consensus on what he said so who are you supposed to believe?). Muhammad never claimed to be God.
We all follow what we wish to follow. We all have our reasons.
If we think that all we see can manifest itself without reason or purpose, then that is our claim.
The best an honest person seeking the truth can do is to work with the best information he has at the moment. The way I see it, God should give all who seek him all the information needed to find him, and a voice from the sky will do that better than anything else.
