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?

planet means “wanderer”
stars essentially have fixed positions in the sky, but planets move. when you see Venus (the morning star or evening star) you’ll note it’s position changes throughout the year because it’s moving.
stars, OTOH are so far away they are essentially stationary.
