Man is looking for some intelligent life out of this earth i. e. In space for long. . And has closed its eyes on d marvellous intelligence shown by other species on earth itself. Look at the plants who can sustain themselves whole life using air, water, sun and earth only. These have abilities to reproduce themselves without moving n mating.
One such reason for searching other intelligent life might be to take control of such species because it is tried n tested method of human beings. Humans have tried making slaves all species of earth including humans and they want to extend this adventure furthermore in space.
Readers of this blog might have their opinion that by searching other intelligent life forms we can share each others technology for the mutual benefits, but i dont agree. Reason is, if it is the reason for adventuring into space, humans must have first imbibed and used truly marvellous technology found on earth to the fullest.
Has it found a way to artificially produce the technology of producing clean air using raw cells, as plants are doing from thousands of years.
Has it found the technology behind how some reptiles re-grow their organs and even plants that can flourish all through the years. Some trees have ability to live hundreds of years.
Even the complexity of our brain, our consciousness, from where it comes, how birth and death occurs, what happens to the consciousness after death. Supernatural, non-physical phenomena, etc.
Every such thing is out of scope. Yet there is enough curiosity to find other life forms in space. . . Why? To rage a war and make them slaves.
