What is required for life to exist on our planet is extremely complex, intricately balanced and fine-tuned in relation to the size and position of the earth, the sun, the moon and other planets, the earth's magnetosphere and various atmospheric layers, the abundance of water, various oceanic and weather patterns and even the temperature, size and properties of the earth's inner core. And, this is only a small fraction of the balanced complex reality necessary for our existence.
Because of this, some scientists still insist life may be extremely rare in the universe. But it appears exo-planets may far outnumber the stars and today, many if not most scientists believe life is probably abundant in the cosmos. Perhaps few of us stop to consider how truly different, diverse and complex life in the larger universal reality, may in fact be.
At least one scientist has proposed life might exist on giant gas planets, hovering in the atmosphere with no need of a solid surface. We often assume far too much based on our own tiny window of experience while, the experience of intelligent beings on other worlds may be far different than our own.
Most books and films featuring aliens assume beings more intelligent than ourselves would have superior technology and travel in advanced starships, which isn't necessarily true. They are often portrayed as creatures prone to violence and oppression like ourselves, which also isn't necessarily true.
Human technology arises out of our specific needs for survival. While other forms of life on earth build webs, nests and some even use sticks as tools, what is called "technology" is essentially viewed as being unique to humans. If food was easily and readily available and there was no violence or daily struggle to survive, human technology might not have ever arisen on earth.
Would beings more intelligent than ourselves necessarily have any concept of science and education? Would they wear clothing or need to build structures for protection in a perhaps far less hostile environment? In a world without living beings eating each other, without war and other oppression or struggle for food, shelter and protection, would there be any such thing as "survival of the fittest"?
Does science chain our brains in far too narrow of a box? You decide.
