Informed readers will be aware of the theory that a Red or Brown Dwarf companion star to our Sun, which has an enormous and elongated orbit, causes periodic disturbances in the Oort Cloud every 30 million years or so and sends cometary bodies into the inner Solar System, some of which collide with planet Earth.
These impacts were responsible for the great Permian/Triassic mass extinction, several minor Jurassic extinctions and of course the Cretaceous mass extinction, followed by a further two minor extinctions.
The cyclical nature of such extinctions implies a periodic cause, with the result that a small, faint and hitherto undetected companion star to our Sun has become chief suspect.
However, though these events may be periodic, Dr Cometencke contends that they may not be naturally occurring but instead carefully contrived by a long lived alien race as a VERY long term plan to genetically modify life on Earth.
The fact that crocodiles survived the extinction of similar creatures - the dinosaurs - he regards as highly suspicious. He said that crocodilian jaw structure changed overnight at the Cretaceous/Tertiary boundary resulting in a larger cranial cavity and brain size.
He theorises that thousands of crocodilian eggs were taken off planet just prior to the Cretaceous impact, genetically modified and after long term storage returned to Earth to fill the ecological niche vacated by the dinosaurs, who, after long experimentation during the Triassic, Jurassic and cretaceous were rejected and the slate wiped clean.
The Nemesis Star, he suggests, is brought in by a tractor beam when required to divert suitable comets Earthwards.
He said that this genetic manipulation suggests that the aliens were a saurian species, or at least compatible both with dinosaurs and crocodilians.
He came to Australia to examine crocodilian fossils laid down at Riversleigh over the past 15 million years to see if the pace of change has altered.
He is alarmed by the possibility that the unexpected success of egg eating mammals, and of course the human mammal has derailed this grand plan and that these aliens may decide to clear the board once more.
An allied line of research is being pursued by Kibbitzer Prize winning author Lucy McKilroy, who accompanied Dr Cometencke to Australia.
She was gathering material for her new book titled: "Vice Presidents From Outer Space".
Lucy had noted the phenomena that most Vice Presidents since 1788 seem to have vanished without trace soon after leaving office - and in fact one or two while in office.
She avers that she has evidence that many had returned to their home planets after completing their missions on Earth, their principal mission being to starve the Near Earth Asteroid Survey of funds so as to facilitate Earth being attacked without much notice by rogue asteroids.
The historical record shows, she said, that no funds were allocated for a Near Earth Asteroid Survey from the Presidency of Washington to Nixon, while she suspects at least two Vice-Presidents to be androids with defective circuits or generators.
Lucy agrees with Dr Cometencke that a Brown Dwarf is currently about one light year from Earth, somewhere in the vicinity between Earth and the LMC to limit chances of detection. She visited Australia to examine certain inscriptions carved in Coptic on a petrified fossil of Wollemia Nobilis (Wollemi Pine) concerning ancient legends about leaders from the stars whose mission is to usher in cycles of destruction on planet Earth.
Lucy's book will be launched on completion at a ceremony at the Roswell Bar and Grill, after which she and Dr Cometencke will depart for a lecture tour of the Southwest, commencing at Pop's Restaurant, Fort Davis.
