Once upon a time, an alien spaceship landed on Earth. A little girl was the first to see it. She wasn't scared but curious. She walked towards the strange-looking ship. As she got closer, a small alien peeked out. They just stared at each other for a while, and then the alien made a friendly gesture. It was a moment of pure wonder and the start of an amazing first contact story.
The first Doctor Who story was about the Doctor and his companions getting involved in a time-travel adventure to stop an alien threat.

It forces the human characters to question their own assumptions about these concepts. And in 'Stranger in a Strange Land', first contact is a personal journey for the main character as he bridges the gap between Martian and human cultures.
