Our Lady Of Lourdes isn't the most recent appearance of the Virgin Mary, remember the apparitions of the virgin Mary in Fátima in 1917, where she showed up in front of 3 shepherds and after a series of appearances, the Virgin told the shepherds to tell everybody to a certain place. About thirty THOUSAND people showed up and they all witnessed something known as "The Miracle of The Sun". One of the 3 shepherds, Lucía, survived (the other two shepherds died too young) and Lucía lived in a monastery and had 3 letters with revelations from the Virgin. The church (made a mistake from my point of view) failed to release this predictions when they were ment to be released 'cause they were scared the prophecy was mistaken but the first revelation was accurate (Something about the first world war being about to be over and the comming of WWII. The 2 prophecy announced the end of the second world war and the virgin spoke about the conversion of Russia to catholicism. Now that kind of stuff is cool and I think it's kind of a proof, with thirty thousand witnesses. Naw many people have tried to explain the miracle of the sun but the fact that it happened when the virgin announced it is, from my point of view, a miracle indeed.
If you're believers or not, I think thisone is a great thing to read. Here are some links.
