I try to understand both Mormons and Muslims, and to respect their beliefs while affirming that only through Christ is their truth and salvation. This is difficult at times though, as sometimes their holy books twist the words and understanding that God presents to us in His Word.
I remember reading at one point that the Muslim text in the Ka’abah contradicts the Quran, and wish I could find that reference again.
Oh, further note. If I recall correctly, the statue of one of the Greek godesses that was worshipped (I'm thinking Artemis, but I may be wrong) was thought to have originated from the sky, as was one to Ashtarte/Aphrodite Urania in Aphek.
That earliest Artemis temple at Ephesus contained a sacred stone, probably a meteorite, that had "fallen from Jupiter."
