Hey! Don't go to the malls, schools or outside. Danger lurks. There have been killings, robberies and rapes in these places. Bad people there!!
Don't drive a car. Many millions have been killed in cars. And bad people drink and drive or will kill you with their bad driving.
Don't eat. People have been poisoned with bad food and choking. Bad people have poisoned food.
Don't breath. Your air could have Anthrax or a deadly pathogen from a terrorist.
Don't live. Cause you could die????
Head in the sand is the stupidest form of awareness, or lack therein. The mere argument is laughable.
We are, from all indications, within a massive multi world, multi species, multidimensional civilization. We are also likely one of the most
dangerous species around. Especially if our heads are embedded in sand. Blind, deaf and ignorant.
We cannot "cloak" the planet, and have been sending out radio waves announcing how stupid we are for decades. SETI is good in spirit, but I believe
bad in practice. Radio waves are likely the equivalent to smoke signals to talk to the Moon. Any sufficiently advanced civilization will have found
much more efficient means of communicating. Why don't we use a letter to contact an insect? Silly assumption that only radio waves in the Hydrogen
band are the best shot at saying, Hey, Over here! SETI is blinded by simple logic and lack of funds.
We can't hide, so whats the point? Many of us, very intelligent and official government and civic officers have seen both good, questionable and bad
aliens already. Already in the park people!
It is likely there are some aspectually "bad" aliens here. Like any crowd of people, there is, depending on the city, neighborhood, block, a
certain percentage of people who would hurt you or otherwise threaten your family. So in a very BIG neighborhood like a galaxy, or local group of
galaxies, the chance of a race of beings who like pork-like meat coming all that way for lunch is maybe less likely.
Any beings that would hurt us, would be known by all the other advanced civilizations. And, in some cases stopped by the overall moral and
compassionate races and allied groups.
Now some might use methods we would interpret as evil, but are not necessarily Like we shoot a drug filled dart at a Lion to do studies on the
species to help it. The Lion say's to itself, "Oh crap! Evil poacher! and runs. It is instinctually fearing any intervention, good or bad. Are
we proving to be any more intelligent?
Sorry, but the argument is without merit on a few levels. Have fun with it though.
