How did the internet get started?

The internet feels like it's been around forever — like electricity or pizza delivery. But it actually had a birthday, and a weird one at that. It was born in a beige government office in 1969, when a bunch of scientists tried to get two computers in different cities to say hello to each other. Spoiler: the first message crashed halfway through.
Back then, computers were huge, expensive, and mostly lived in university basements. Each one was like a genius locked in a separate room — brilliant alone, but unable to share ideas. The U.S. military thought: what if we connected them? If one computer got destroyed in a disaster, the others could keep working. So they funded a project called ARPANET to wire a few computers together.
