In the past, before there were any cameras at all, travelers through the forests and sailors on the seas would hear noises and see glimpses of animals in the moonlit night. There are some frightening noises one would hear. With the wind or a falling branch their imaginations could run wild. Wolves passing by in the forest could be thought of as scary beasts. A crashing wave could be thought of as a sea monster attacking the ship. The people back then simply didn't know otherwise. So there were believed to be a whole host of mythical beasts in the world. The Griffin is one of them. For these people the world out there contained unimaginable beasts. Good paintings and the camera eliminated them one by one. The camera never captured them on film. So there was less reason to think they existed. But not all of them were put to rest, and others surfaced.
Now Vandy Beth Glenn at Skeptic Ink Network tells us there hasn't been any sightings of Nessie, the Loch Ness Monster, in a year.
I’m not surprised. I’d bet the number of UFO sightings is also going down, as well as encounters with other lake monsters, Sasquatch/Bigfoot, the yeti, sea monsters, and every other sort of cryptid, alien, ghost, and dubious phenomenon. But it seems uncontroversial to assert that these appearances must be becoming less frequent, and the reason why...is the days of blurred or low-resolution pictures, camera artifiacts, lens flares, and other photographers’ shortcomings are simply drawing to a close. Everyone has a camera on their phone now. Everyone. If five people are on a beach and one of them yells, “What is that?!”, all five will whip out their phones and start taking still images or video. If one of them has a bad angle or their finger over the lens, the rest will get the shots.That's science and technology baby. It works. The similar thing happened to God as we discovered he was not found here or there or anywhere, as Jonathan Pearce correctly summarizes. We can see this best by the scale of the universe itself. The same thing goes for claims of miracles. As modern medicine developed there was less and less of a need to see illnesses as God's curses or demonic afflictions, and less of a need for miracles as the correct drugs and proper surgeries could heal us apart from them. Science and technology are ridding us of the sacred. It's incremental. It does its work continually and effortlessly.
So the question naturally arises why should we take seriously any claim in the ancient superstitious past to a miracle or sighting of God or mythical beasts and angels? I see none.
