Sometimes I wonder!
Why do tears exist in form of liqiud (water) ?
But it didn't take long
Before I got it on..
''scientifically'': this earth lays on water bodies.
''geographically''water covers most part of the earth than land.
''biologically''water possess more part of the human body
''historically''before the earth was created, it was covered with water.
Now you've got my point. Don't you?
