We live in a beautiful planet , created by God.
Some of us enjoy their life to the fullest.
Some were not.But both need to appreacite what they got.
It is not appropiate to live or life without knowing well about the place we live in.
It's like living in a house without knowing how many rooms that we have...and without knowing who is the owner....so..let's begin the journey.....
note : (information taken from http://en.wikipedia.org/wiki/Earth)
Let's get the most basic information of our big home...

Well...for a start...as a warming up for our brain before going further on more details and complexity of our planet...
510,072,000 km² is our planet surface that God created for us.
How much is ours?
How much we got , manage and send back the profit to God?
How many times have we really sacrifice for it?
