Please read my words carefully:
If you see footmark in the sand, you'll say that someone passed from here...
If you see a piece of dog sh*t on the ground, you'll say that a dog passed from here...
So what about the enormous universe, the sky, stars, planets, earth and all the beauty in it, doesn't it lead to that someone made it?!!!
Some people say that everything is created by itself after the big-bang... I won't ask you about what caused the big-bang, but I'll ask you a simple question:
If you take all the letters of the alphabet, multiples of them, and you threw them randomly on the floor. Do you expect (by a chance of one in infinity) to get a poem like shakespear's??!!
Can't you see how organized our universe is, the planets, the eco-system on earth, look even in your own body... Can you control your heart-beat? Can you control your breath while you're sleeping? Who stopped your eye-lashes from growing after reaching a certain length? Who told the baby turtles to move towards the sea and not to the earth after they come out of their eggs? Who taught the bird how to make nests?
My friend, think with your heart and brain. If you're still lost, think about the following:
Do you know how to play safe?
If there's no God and you do all what you want in life, then nothing will happen to you after life. But if there was God and you were mistaken, then you'll blame yourself FOREVER...
If there's God and I followed His commands in life, then I'll be in Heaven after life FOREVER. But if there was no God and we're mistaken, then nothing bad will happen to us after life...
Now you know how to play-safe, in case you're not convinced?
