Be more specific.It's no miracle if you see Africa from Spain, or from Malta,even Sicily i think
I live in Croatia. A couple of moths ago we went to the astronomical observatory with the school, and it was a very clear day so we saw Italy from the mountain.It is also visible from some islands on a clear day.And you don't see all of Italy(with the shores and coastline), just the highest mountains.That actually prooves the round earth theory
Besides, the distance from Croatia to Italy is somewhat equal of the distance from Malta to Africa, Spain is even closer.
