Well I am surprised to find a thread on this subject.  I know many Catholics take apparitions and revelations to heart.  So, to get to the point;  I think that they are both bogus.  Fatima the sun was said to have changed color and danced in the sky.  My reply is and was;  if so it would have been observed world wide.  It was not.  If so, planets would have been flung out of orbit.  They were not.  There is absolutely no true scientific corroboration for any of this stuff...only in religion can this be expected to be accepted and believed.
