Actually, world wide there are reports which go back thousands of years. UFOs are even documented in art work from The Renaissance and by well known scholars. Even Christopher Columbus documents a UFO sighting in his journals as he sought the new world.
More likely why there is no documentation before 1952 is because of the same reason its true (with varying dates) all around the world. Before such a time, no one was charged with recording such sightings.
And for what its worth, crash sites are also reported long before Roswell. Others are reported all over the world, even including Germany, several decades before WWII.
I don't get why you linked to the Wikipedia article about the Renaissance, but this link is a lot more valid to your argument.
