Ambiguity Of The World

The world would have been a better place if we understand more about life, if we know more about what life entails. Tell me why a girl who's not even eighteen will have a romantic relationship, doing things people in marriage are doing? Tell me why on earth will a guy who is not seventeen be looking for money, to the extent of going after money beyond imagination and explanation? Maybe if things aren't civilized the way they are now, it would have been better, and the world would have been a more better place to live in.
