How was the internet first invented without the internet?

The idea of two computers communicating with each other 1 to 1 over a distance already existed before the concept of what became the Internet was conceived. In fact it was the complication of having to swap computers or disconnect and reconnect if you wanted to change which remote computer you were talking to that inspired the internet.
Basically I’m the late 1960’s a group of computer researchers decided to try and solve that problem. They met multiple times and came up with the early protocols (aka communication rules) and designs that would be required. The presented their ideas at conferences, got feedback from other computer researchers and refined their ideas.
Eventually, in 1969 the first communication between two computers on ARPANET, the precursor to the modern Internet, occurred when a transmission was sent between one computer at UCLA to another at Stanford. By the end of that year two additional nodes, one at UC-Santa Barbara and another at the University of Utah were added.
From there things continued to grow as more nodes were added and more networks were connected using the agree upon protocols. So like most projects it started out small and then grew from there.
