Valmiki wrote the ramayana who lived during ram's time. According to wikipedia, Ashok Banker's Ramayana is "A contemporary novel, it is an epic hard science fiction story about a war between the gods of different faiths. Weary of the constant infighting between religious sects and their deities, God (aka Allah, Yahweh, brahman, or whatever one chooses to call the Supreme Deity) wishes to destroy creation altogether." That says it all. It's contemporary fiction. Hindus have respect for valmiki's ramayana, not this Banker's fiction.
