The Quran. Is it an eternal word, or has it been abrogated? How can both be compatible?

The Quran is not a religious book, it is a diary of wars, and rights for women, and permission to fight , curses on the infidels polygamy galore and fairy tales about ants that talk, it is all invented by the man who claimed to be a prophet this man is Muhammed, who wanted to conker the known world at that time
