The perturbations of the outer planets 'downwards' have been known for a few decades. The cause is the mystery. A brown dwarf star is a reasonable culprit. It is virtually invisible without the use of infrared telescopy. It is theorized that it would react with the sun when it breached the outer solar system and burst into a red fireball. NASA engaged a USAF C141 Starlifter fitted with infrared equipment to scan the outer atmosphere during the 1980's. A claim was made circa 1983 that they did sight it. (A Rand think tank spokesman has recently and openly stated that no public warning would be issued if the authorities knew of an impending celestial disaster.) A report got issued from a NASA source (as I recall) and one of the newpapers which carried the story was Melbourne, Australia's HeraldSun. A military fellow stationed in Guam in December of 1982 (again, as I recall) also confirmed the veracity of these flights.
Your colorful analogy is mute when one considers the recent large comets(NEAT) and a NearEarthObject that caught every star-gazer off guard. Presently, the sun is exhibiting incredible solar flaring. I presume you know about this. What causes this no-one is venturing to say.
I guess I'm one of those whom you labelled "hard-heads" that believe in The Great Flood. Insofar as population demographics go the archaeological evidence suggests that pre-flood populations were global and millions, if not billions. The hard evidence exists in archaeological and geological discoveries. Mathematically, it is feasible, discounting wars and pestilences,etc., that world populations could well exceed today's 6 billions commencing from one couple as close as 5000 years ago. The survivors of The Great Flood knew of the conditions in the pre-flood world and their descendants took, and in some cases embellished, the stories they were told as they moved out around the world. The similarities of flood stories around the globe is thus not too difficult to comprehend.
Harrington said it would more likely be sighted in the Scorpius constellation, while myth and others claim it would be sighted in Taurus. McCanney currently says that he has sighted nothing which resembles a PlanetX type of stellar body.
