take an example of two people,, any religon and group u choose... give them a task to draw any one picture, lets say picture of Palm Tree and write an essay on Palm tree.. There Picture's size, colors, combinations, number of scatches, amout of time to complete, will be different... and anyother can tell the difference between both pictures even though both had drawn palm tree on a paper..similarly both explaining about palm tree, but using their own words/sentences... whereas We don't see any difference in this Universe among any CREATURES, which leads us to the conlusion that thir must be ONLY ONE CREATOR who created them so perfectly..
