The Lochness Monster exists.
In order to explain scientifically to a non-believer that Nessie exists, one must refer back to much historical data dating back to the Phanerozic Eon, and specifically the Cenozoic Era. 66 Megaannum it is believed that a Cretaceous-Paleogene extinction event occurred, based on the presence of iridium in a specific geological layer of the earths crust, it is theorized that the event was asteroid/meteorite impact related. While it is undeniable that such an event took place and eradicated many animal species, the specific species that were impacted is arguable.
Throughout the 1800 and 1900's documentation in regards to the Plesiosauria was discovered through fossils widespread over several continents. While it has previously been assumed that the Plesiosauria was included in that mass eradication, there is no scientific proof that this statement is more than mere theory. There HAS been scientific evidence that avionic decedents of dinosaurs survived the Cretaceous-Paleogene extinction event. And even better than evidence of birds, we have undeniable proof of a few plesiosaur that made it through the horrid wipe-out of the earth.
For instance, in 1988 in Monterey Bay, California a one Dr. Hovind identified the body of a Plesiosaurs washed on shore. Additional documentation of dying, dead Pleasiosaurs dates through out the 20th century. Due to the natural speed of such animals, it's not a wonder why we have yet to capture one alive!
It is arguable that due to the it's local over the Great Glen Fault, that this area was not impacted by the Cretaceous-Paleogene extinction event, but due to the nearby location of s aluminum smelting plant and poor environmental practices during the iron age, it is difficult to extract any geological information from the area. However, there is no arguing that Loch Ness is the deepest Loch in Scotland, and that with it's connections to nearby oceans, we can be undubily sure that a Plesiosaurs could reside in such a Loch, in fact because of the size, several Plesiousaurs could reside in there, we just only have one name for them all....Nessie.
