Doesnt alien mean that something not originated on earth ? So if you think in that perspective Allah is an alien, as he is not originated on earth. He has always existed, he created the earth so yeah. And not originated on earth means that Allah is not a man made god, as he is not originated in earth. In that sense telling that Quran is written by aliens is proof that it is not a man made book. They are refutating themselves(Noobs). -.-
We are talking about extra-terrestrial aliens that exist in this word. Allah is not an Alien because he doesn't exist in this universe. He exists outside of the universe and he is the maker of the universe.
But yes, I've heard the fact that the Quran being written by aliens so many times and they are refuting themselves.
