Beauty of nature

I am born nature.
I light the whole day and never get tired.
I am the light in the darkness but stilll not complain.
We decorate the sky in the night though we can't light the world like the mood.
I flow from rivers to the sea, yes I am a beautiful creation.
August is my month though am not proud of ruining your day eveytime I pass by but I am bound to wind.
Will never leave the world alone, will be there day and night to support.
