Verse 42:23 and how to interpret it, disciplines of interpreting Quran.

[pocaracas]

Whatever reason is given to any of those questions, it is given because of the patent absence of any divine creature on Earth.

It is clear that only people can pass on the information of god to other people.

What you said is true. There is only one God and his name/face from humans must be what guides humans and God manifests proofs, and there is no divine creature, rather only divinely appointed creatures from the earth in the form of what is termed "humans".

I know you can't understand this, but those "divinely appointed creatures" have very very very likely not been appointed at all.
Like Joseph Smith, the founder of Mormonism, like L. Ron Hubbard, the founder of Scientology, or like many others that time has forgotten, they are simply charismatic people who manage to get other people following their ideas... and, of course, if they can convince their followers that they were divinely appointed, then they're golden and set for an eternity of believers.

Note that no actual "divine appointment" is required to get people to follow; no "divine appointment" is required to write nicely sounding behavioral rules for a society; no "divine appointment" is required for people to perpetuate the belief that the person(s) is(are) "divinely appointed".

A divine appointment and a lack of such divine appointment are formally equivalent to their followers. All they need is to believe that there was a divine appointment.

Still, no god worthy of that name would require a few select people to carry its message. It would carry the message itself. We don't see that happening... never has, and I doubt it ever will.
I'll ask again,
