from our every day experience we know that every machine or system needs continuous maintenance by human beings.
a car may need some maintenance from time to time.
a factory should be supervised by some humans regardless by the level of advanced technology applied.
every (working system) made by human needs continuous supervision and maintenance, otherwise it will degrade continuously.
now, think about this world we live in.
it is a highly-complicated (factory), where millions of plants, animals and humans are created every year. the system provides enough amount of oxygen in the air and continuous supply of pure water by rains to sustain life.
this factory works from very long time.
so do you think it is possible for such complicated system to work all this time without any supervision or maintenance? and why you think so?
