Because of radiation dangers in space only properly designed machines could travel for any length of time. So UFO invaders would most likely be enamored with your car, lawn mower or vacuum.

Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying.

Both are equally true!
No matter how many life forms living on other planets, moons, or even stars, We are inevitably ALONE.

man thats sad...
anyone who thinks that we are 'ALONE'
is an emo ¬_¬

I agree with Steven on that one -- You can be alone while surrounded by people. Sometimes alone = lonliness. And for Steven's statement we will probably be alone even though there may be billions of intelligent species because either a) there is no way for us to travel to them or them to us, or 2) there is no way for us to communicate with them, something like us trying to talk to an ant.

Thank you, I did post a rebutle to that emo statement but it included a few choice words that i recieved a warning for.

Must not live in the US - I have never paid extra insurance for my red car and got only one speeding ticket in the 18 years I owned it. Before you ask, I was born and raised in Montana where the speed limit was reasonable and prudent (ie. no speed limit), I drive fast. I am not an aggressive driver but I am assertive. Er, I actually talked my way out of that speeding ticket by claiming that, since I was born and raised in Montana with no speed limit, I depended on my cruise control to control my speed and that my cruise control broke on that trip. I was looking for a defective equipment ticket but the judge just looked at me for a long time and said "I have never heard so much crap but, I am going to give you the benefit of the doubt and if you get no moving violations in the next 6 months, your record is clean" charged me $50 court costs. I talked my way out of a couple other moving violations but that was in a volkswagon and does not count.

No one has ever come up with any actual citations for the "red cars get more tickets, red cars cost more in insurance" stuff. I want to see any actual (actuarial) stats. If a red car in your country costs more to insure, I want to see the actual policy wording that says "we charge xx more for a car that is red". Do they charge less if the car is burgundy? How about orange? Does someone take color readings to determine how much red is in the color and then rationalize the %age of red?

ask anyone in the UK. Men, especially men under 25 who drive red cars generally pay more

the claim that civilizations could never travel to, what is more, communicate with other interstellar civilizations is to assume the current state of human science complete and the universal epitome par excellence.

as much as humankind does know of the universe, it knows next to nothing. human science is far far from complete and interstellar travel and communication will reveal itself given time and the perseverance of great minds of course.

as to whether or not we are alone ... i cannot imagine it to be so. life is too abundant and too resilient on earth and possibly within the solar system to be devoid throughout the cosmos. i have mixed beliefs about the authenticity of ufo sightings. i do not exclude the possibility that some are legitimate, but am more inclined to believe ufos (the kind that are not obvious hoaxes) are government experimental craft.

The non-hoax UFO sightings are most likely caused by drug induced hallucinations.
