I think you have to figure in what happens if people find out what really happened. Then:
-
Macron is over;
-
France is in revolt;
-
The Vatican? People don't usually burn down their summer house;
-
Terrorists? Igniting a religious war holding a minority position is suicidal;
-
Good guys? Good guys don't burn down a revered landmark;
-
Accident? In two places at once? Doubtful.
-
God? God destroys things utterly and completely; this is not His work.
