I ask because when scientists ponder whether there is life elsewhere in the universe what exactly is the criterion they use? I mean, can't all things, even down to the atom, be considered a form of life - albeit a simple one?

The wonderful thing about science is sometimes the scientist don't know what they've found. The most recent example is the researcher who was annoyed that her cells were dead. A collegue was astonaged, "You killed your CANCER cells?" Initially she didn't realize that she may have found a cure for cancer. That is truly a defining moment for all of us.

i imagine, technology is the theoretical clarification of factors and motives yet no functional progression is accessible. notwithstanding, faith isn't an excellent in the recent era because it has defined in diverse thoughts innumerable circumstances. faith advices a uncomplicated existence-form that makes the society at the same time and united and each and every human being has to save on with a similar subject matter. technology helps human being and faith helps the community, it truly is meant for the society. utilization of 'diverse community' is incorrect as same classification of workers belong to an section and not in any respect the different, operating example Railway Chaprasi - is an section or classification, IAS cadre is a classification of workers (employment) and as such those will be called as an section as become used lengthy lower back. notwithstanding, both are imitative and smart can take income on them until eventually regulation and order situation isn't mainained.

There is no set definition to life but there are characteristics of life. Things of life respond to the environment; internal and external stimuli, reproduces (gives life), it grows, it uses energy, has a cell...yes, one cell because the cell is the basic structural unit of life.

They undergo metabolism; possess a capacity to grow; respond to stimuli, reproduce and through natural selection adapt to their environment in succeeding generations.
i.e. a rock is not considered life because it doesn't have the capacity to grow, reproduce, or carry out any metabolic processes necessary to life...
