When a human child comes to this world ,the External world is wiser , stronger and more more beautiful than us.
the most practical ways of development for human are based on experimenting the outside world. the source of knowledge is outside human as well as beauty and power .
Even the source of life and energy is outside the human .it seem that beauty , power and wisedom are three faces of one fact.we just tend to name it in three seperate way.

so there must be an intelligence outside , with greater intelligence of us which have set the rules for the nature to make it beautiful and mighty and wise. the rules are constant and also good. whatever we think ,these rules do exists .

the nature is in a great harmony so we can understand the great source of wisdom ,beauty and life must be the same.
If we follow the wisdom it continues around galaxies , also beauty and power. Even we understand there are great powers all in harmony ,that our galaxy is nothing in fornt of them. so this source is really great.
