Time zones in America

Why does America have several time zones

If America is every one country, why has actually it been separation into several various time zones? as you may have actually noticed, America is a super huge country. Well, big compared to mine anyway.Time zones were created by train stations, that would each have their own clocks at the end of the 1800s. Yet this made it difficult to name: coordinates schedules. The original solution was to have actually 100 rail time zones.
