If I look into the sky and I see two yellow dots it’s all stars for me. Then I hear one of them is mars and I’m like „ok, still looks the same“. How did the people hundred of years ago discover what’s a close planet and what’s a far away star?

Mars could be seen with the naked eye, but the invention of telescopes really pushed the field forward.
Telescopes required (at the time) complex glass production. As a result planetary discovery heavily relied on a large established glass industry that could make the types of specialized curved lenses the teslescopes required. This limited astronomy to some parts of the world only. Chemistry entirely relied on glass as well and also ended up a geographically limited scientific field, but that’s a different topic.
