Continue - Ender's Game

I have never liked science fiction stories. When I was child, there was one possibility for us as children, just real relationships in society and families; watching cartoons in which animals played the role of humans, good against bad,  protagonist against antagonist, a child looking for their mother, poor children with ambitious dreams. I remember that the most attractive cartoon that I watched was Rabin Hood. All of them were about the people's relations and responsibilities. I never thought that how these kind of cartoons and movies affected me, and I think I found the answer right now. I read the introduction of the book in which the writer explains how the book has affected the readers. I couldn't make sense. Then started to read the first and second chapters. I am not encouraged to continue reading the book because I can't understand the meaning of unknown enemies of the world; strange creatures with extra-power who want to indwell(!) the earth. For me as an Iranian with a long cultural history, the enemy is not far from humans. During the history, there had been great killers like Genghis Khan and Hitler. Enormous people were killed because of diseases, like Malaria, Typhoid, Pest, and AIDS. Millions of people have been dieing due natural disasters like famine, floods, earthquakes, and tsunamis. But even one person has never been killed by a spacial creature.
In my mind, there are many lost desires; my childhood dreams, my memories of my cousin who died 20 years ago, my parents who I devoted my life for their wishes, my friends who all of them are busy with their own problems, my life that I never paid enough attention to; so there is not any opportunity to a science fiction story to catch my interest. Poor Ender! I usually read poems of Iranian poets. One of the main characteristics  of Farsi language is that during more than 1000 years, the grammar and words haven't changed a lot. Therefore, every typical readers can read and understand poems from great poets like Hafez, Sa'di, Khayyam, Molavi and Ferdosi. Iranian people usually look for their dreams and their history in these poems. God, love, respect to family and parents, friendship, life and death. There is no history of spacial creature in our culture. All the antagonists are symbols of brutal behaviors of humans like jealousy, lying, betrayal, and ignorance.
I can't continue reading this book because I can't think about something that has not any connection with my emotions and desires. It is not an excuse, it is the response to the unasked question that why I never have liked science-fiction stories and movies.
