In the early afternoon of
26 April 1803 ameteorite shower of more than 3000 fragments fell upon the town of L'Aigle inNormandy (France ). Upon hearing of this event the French Academy of Sciences sent the young scientistJean-Baptiste Biot , to investigate on that spectacular fall of stones. After an accurate work he reported two kinds of evidence of an extraterrestrial origin of the stones [ [http://www.lpi.usra.edu/meetings/metsoc2003/pdf/5251.pdf M. Gounelle. "The meteorite fall at L'Aigle on April 26th 1803 and the Biot report.] ] :
# "Physical evidence": the sudden appearance of many identical stones similar to other stones fallen from the sky in other places
# "Moral evidence": a large number of witnesses who saw a "rain of stones thrown by the meteor"Upon hearing the Biot report about this meteorite fall, the French Academy of Sciences sent Jean-Baptise Biot to investigate. His passionate paper describing how these stones must undoubtedly be of extraterrestrial origin effectively gave birth to the science of meteoritics.L'Aigle event was a real milestone in the understanding ofmeteorite s and their origins because at that time the mere existence of meteorites was harshly debated and witnessed meteorite falls were treated with great skepticism.Composition and classification
