Maybe.
Another option is that the original “Mecca” was actually Petra. Early prayer walls in mosques point towards Petra (not Jerusalem) and that city better matches the descriptions given for “Mecca”.
Have you read that theory by Tom Holland? To me it sounds highly plausible that Mohammad never existed.
that word is a title not a name - a title meaning “praise worthy one”
And there is no mention of Mo or Islam during the Ummayyad Caliphate.
