Can Rocks Fall from the Sky? Many Astronomers Resisted the Idea

Essay

(The tide turned in 1803 when several thousand stone fragments fell to the ground near L'Aigle, France, in the presence of hundreds of witnesses). Suppose that, for whatever reason, no meteorite falls could ever be witnessed. Would it still be possible to make the scientific case that some rocks on the Earth had to have fallen from interplanetary space? How would you make this case?
