What is Earth without the biosphere?
The universe is a pretty big place. It's bigger than anything anyone has ever dreamed of before. So if it's just us... seems like an awful waste of space. Right?
Dolphins are social, living in pods of up to a dozen individuals. In places with a high abundance of food, pods can merge temporarily, forming a superpod; such groupings may exceed 1,000 dolphins. Individuals communicate using a variety of clicks, whistles and other vocalizations. They make ultrasonic sounds for echolocation. Membership in pods is not rigid; interchange is common. However, dolphins can establish strong social bonds. Dolphins will stay with injured or ill individuals, even helping them to breathe by bringing them to the surface if needed. This altruism does not appear to be limited to their own species however. The dolphin Moko in New Zealand has been observed guiding a female Pygmy Sperm Whale together with her calf out of shallow water where they had stranded several times. They have also been seen protecting swimmers from sharks by swimming circles around the swimmers or charging the sharks to make them go away.
Dolphins also display culture, something long believed to be unique to humans (and possibly other primate species). In May 2005, a discovery in Australia found Indo-Pacific Bottlenose Dolphin (Tursiops aduncus) teaching their young to use tools. They cover their snouts with sponges to protect them while foraging. This knowledge is mostly transferred by mothers to daughters, unlike simian primates, where knowledge is generally passed on to both sexes. Using sponges as mouth protection is a learned behavior. Another learned behavior was discovered among river dolphins in Brazil, where some male dolphins use weeds and sticks as part of a sexual display.
Dolphins engage in acts of aggression towards each other. The older a male dolphin is, the more likely his body is to be covered with bite scars. Male dolphins engage in such acts of aggression apparently for the same reasons as humans: disputes between companions and competition for females. Acts of aggression can become so intense that targeted dolphins sometimes go into exile as a result of losing a fight.
Male Bottlenose Dolphins have been known to engage in infanticide. Dolphins have also been known to kill porpoises for reasons which are not fully understood, as porpoises generally do not share the same diet as dolphins and are therefore not competitors for food supplies.
“I suspect there could be life and intelligence out there in forms we can’t conceive,” he said. “Just as a chimpanzee can’t understand quantum theory, it could be there are aspects of reality that are beyond the capacity of our brains.”

Our overall presumption is that if alien life exists somewhere else in the universe, they would presumably be of a higher level of intelligence and spirituality. Again, I'm not saying that they don't exist, its just I can't see them as being malevolent. We as humans are the most malevolent race in the universe. Now, while that could lead logic to tell us that other species could be malevolent as well

I think OrionHunterX said exactly what I think is probable. I wouldn't go as far as saying that it's a fact 'tho.
And maybe these (hypothetical) aliens aren't even using technology that uses radiowaves. They might have also figured out that it's destructive to mess with the natural evolution of another intelligent species.
But to assume they wont would be great folly if in fact they do.

I think the biggest problem is that people - including Stephen Hawking - tend to use their knowledge of human and human history when talking about ET's. just because we seem to love war and conquer, doesn't mean the aliens necessarily will...

Mankind uses his five senses to determine reality. Hundreds of thousand witnesses had over the century determined their own reality. One person may be hallucinating, but hundred thousands hallucinating the same reality would be impossible.
I believe that it is widely thought that our present-day radio/TV broadcasts would be indiscernible against background radiation at distances beyond 2 light years. None of our spacecraft have yet traveled beyond a mere few billions of kilometers from the earth, and they ain't gonna get anywhere anytime soon either. We may not yet have let out the secret of our existence.

i am familiar with some of Steven Hawkings views on the subject, and i agree with him on much of it. But, we are televizing broadcast signals in space and have already launched objects out into space. they will/do know we are here.
Originally posted by tdatreefrogI agree with the probabilty of advanced life existing. Like a previous poster said however the main issue is time. I personally believe that time is the reason that although there may be hundreds, thousands, millions or more advanced civilizations none of them have had enough time to advance their technology enough to close the unimaginable distances between these civilizations. Maybe there are interplanetary travelers but I think the odds of a civilization advanced enough to travel the vast distances to us is even more slim.
