Gaiman masterfully weaves a narrative where gods are real, their existence fueled by the belief of their followers. As immigrants arrived in America, they brought their gods with them, but in a modern world seduced by the allure of technology and consumerism, these "Old Gods" find their power waning. This theme forces us to question what we worship, consciously or not, and how our collective belief shapes the world around us.

"American Gods" is interwoven with the stories of immigrants who arrived on American shores, bringing their beliefs, traditions, and gods with them. Shadow's own journey as an ex-convict trying to rebuild his life becomes a microcosm of the challenges and triumphs faced by generations of immigrants striving to carve their own piece of the American Dream.

The brewing conflict between the Old Gods and the New Gods represents the struggle between tradition and modernity. The Old Gods, rooted in ancient mythologies, find themselves increasingly irrelevant in a world obsessed with celebrity, technology, and instant gratification. The New Gods, representing the seductive power of the modern world, are ruthless in their pursuit of dominance. This clash explores the timeless tension between the past and the present, forcing us to confront the price of progress and the enduring power of ancient beliefs in a rapidly changing world.
