What we humans are doing?
Just forget about everything that you know and you think. Make your perspective wider and only then you will be able to see what they are doing.
I don’t know why they called themselves the most intellectual and wittiest organism, in my opinion every organism, even every individual is unique and has a unique quality that nature gives.
They think they are smarter because they are able to make aeroplane, telescope, rocket, satellite and many more revolutionary inventions and technology, but don’t you think that they are doing this because of evolutionary brain, straight body design and finger grip that are developed through natural selection and natural evolution.
Now a day they think that the nature and human are two different things. But it’s too clear that humans are only a small part of this massive nature, a lot of creation of human made loss of population and extinction of part of the ecosystem and even continuously creating disturbance in biomes. This is actually not bad thing that the ppm of pollution increase, river lakes getting contaminated, glaciers melt, plastic and carcinogenic material made mutation and cancer in little organisms and even some higher once because all this reaction given by nature is not action of human but a natural process of nature, all these adverse effects are only affect human and related ones, not nature. Human run a lot of campaign regarding safe the nature, I don’t know why they want to save the nature instead of this they should save themselves from adverse affect of their own action either done mistakenly or intentionally. Yet humans are the species who think very well and know how to get maximum outcome from available resources so yes they are performing those experiments intentionally that are Lethal not only for themselves but other organisms for many generations, I am talking about those accidents of nuclear power plants and atomic bombs.
Life on earth is sustained even after extinction of all the things, yet another different life form probably that makes the energy from hydrogen, respire from nitrogen instead of oxygen and having changed metabolism, body physique, everything will change. But the thing which never changes is the lifeform of nature. Nature is enormous and Nature is God.
Biologists may know only what they observe and study available organisms present on Earth but what about those organisms that have totally different anatomy, morphology and physiology, even having unique metabolism. That can sustain even in any severe condition including radioactive decaying conditions. If my assumptions are true then it might be possible that there exists a lot of alien lifeform on every planet.
