Why are humans so anthropocentric to assume that an alien visitor has to say hello?
Do we say hello to the animals we study? Do animal researchers say “hello” to the gorillas and chimps they study? No they don’t. they observe, and try to not be seen.
the only reasons i have seen “skeptics” come up with are either “contact” or “invasion”. that there aer a myriad of other possibilities for visitation, they conveniently ignore.
To quote nuclear physicist Stanton Friedman:
“Think of all the people going through O’Hare Airport in a year and the huge variety of reasons for travel. To get the ball rolling, here are some reasons for coming here. I am sure the reader can think of more.
A. Graduate students doing their thesis work on the development of a primitive society, on a planet where, amazingly, there is no planetary government, and where there are many different languages; on various strange biological specimens, or on genetic variations of the intelligent beings.
B. Broadcasters with weekly shows such as “Idiocy in the Boondocks.”
C. Mining engineers similar to those who went to California and the Klondike and Australia for gold, or to Texas and the Middle East for oil. As it happens, the earth is the densest planet in the solar system, so would be expected to have more of the rare but very important very heavy metals such as gold, uranium, rhenium, platinum, tungsten, osmium, etc. These are all much denser than lead. We know from studying star spectra that they are rare. They also have very special properties.
D. Mining engineers extracting more common metals from the nodules on the bottom of the ocean and from the asteroids between Mars and Jupiter. We have been talking about doing this. Obviously war is much more important than ocean mining to us, so we build nuclear submarines to stay in the depths of the ocean carrying their multitude of nuclear tipped missiles. There are also abundant supplies of so-called rare earths, many used in the electronics and nuclear industries. It should not be forgotten that a century ago the primary use for uranium was to prepare yellow glazes for pottery. Zirconium and titanium were essentially worthless. Now nuclear navies use zirconium based alloys because of their splendid nuclear and anticorrosion properties. Titanium is used in aircraft like the SR-71 because of its high strength and low density.
E. Operators of refueling and rest and relaxation centers on the back side of the moon or in the depths of the ocean or in the asteroid belt.
F. Visitors checking on old colonies established by their ancestors. Perhaps there were many different ones which might explain why we have black, brown, red, yellow and white races.
G. Jailers. This may be a penal colony on which aliens dropped off their bad boys and girls and that is why we are so nasty to each other. Georgia and Australia were first settled by convicts. Letting the convicts go bother other civilizations who, unlike us, have learned to live peacefully, may be a no-no in the galactic rule book.
H. Vacationers. This may be a recreation center. Notice how many people visit Hawaii and Las Vegas and Orlando. If the travel wasn’t easy, how many would venture forth to see Mickey Mouse or gaming tables or surfing beaches?
I. Specimen gathererers for ET zoos and aquariums. We are still finding new specimens.
J. Local galactic horticultural societies collecting specimens for their displays and genetic cross breeding.
K. Medical researchers. They may have to evaluate the genetic material of loads of specimens to find genetic defects or super-special genes. There are a number of conditions whose frequency in the population is quite small (for example, only one person in 14,000 has hemophilia) so many specimens must be checked.
L. Honymooners. Perhaps this is the honeymoon capital for this corner of the neighborhood. Special rates for a week on Earth… side trips to the moon and Mars…
M. Cartographers. Local neighborhood maps may describe, for example, the equivalent of English coaling stations in the 19th century.
N. Sports enthusiasts. There may be special excursions to observe various such events. Don’t forget that a World Championship Chess match was held in Iceland.
O. Scouts seeking the best site for a new amusement park in the solar system.
P. Weapons inspectors. If we make the eminently reasonable assumption that every advanced civilization is concerned about its own survival and security, than we would expect that our development of Weapons of Mass Destruction and the means for delivering them in the local neighborhood would be of great concern. Clearly after World War II it should take less than a century for us to master fission and fusion and other new technologies to allow us to take our brand of friendship/hostility… out there. Thus, a logical reason to visit is to quarantine us until we develop a technique for learning to live at peace with each other. No galactic federation new-member committee would allow us to join. Too primitive.I suspect that the SETI cultists think they would be welcome guests. Not very likely.
Q. Producers. Having worked on a lot of motion picture documentaries at many locations, I would suggest perhaps some visitors are planning epic fiction and factual movies for film companies at home… shooting on location hither and yon.
