Mercury, Venus, Earth, Mars, Jupiter and Saturn can all be seen with the naked eye, so whoever the first human who looked up at the night sky millions of years ago 'discovered' them. Uranus was discovered in 1781. Neptune was discovered in 1846. Pluto isn't officially a planet anymore but it was discovered in 1930.

Yes, the visible planets Mercury, Mars, Venus, Jupiter, Saturn, were known in prehistoric times.
Earth was just discovered in 1982. Before that scientists thought we lived on a burrito.

The planets out to Saturn have always been known. Then Hershel was messing about with the mirror of his telescope and found Uranus
