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?

The planets are extremely bright. Of the five known to the ancients, all of them except Saturn can appear brighter than any star other than the sun. If you’re regularly outside at night they’re all very conspicuous.
