The problem of pain and suffering

What is pain and suffering and how would you counter the argument that there is a god? <br><br>Is god still a loving god if he has created so many animals that are born into a world of suffering and die, only to live for a day or a few years to be euthanized by their own body. <br><br>Why do babies get cancer and die in such a young age, if god is still loving then he must not exist.
