Ancient people, when they started looking at the nigtht sky, would have noticed some of the sparks in the sky behaved differently - that they didn't twinkle and moved against the background of the other stars.
The ancient Hebrews, Egyptians, and other ancient cultures learned to study the movements of these objects and named them "planets" which means "wandering stars."
The first person that determined that they were actually worlds of their own orbiting the sun was Galileo and others in the 1600's.

Nobody knows who first saw the planets. Five are visible with the naked eye. The word "planet" means "wandering star." Galileo was the first to identify planets in a telescope and even after proving to the pope that there are objects that orbit other celestial objects was placed under house arrest. I hope you're not Catholic.

Early astronomers noted that planets move (and appear) differently to stars. They noted the closest planets to us, Venus, Mars, Jupiter and Saturn. Mercury is harder to be seen as it appears near the sun (as its so close to it.) So these have been known about for thousands of years.
After that it was later astronomers who discovered them. Galeleo (1600's)constructed the telescope and first saw the moons of Jupiter but it was Herschel who first saw Uranus (1781) . I know Neptune was mathematically calculated to be in a place and then later discovered in about 1800. In 1930 Pluto was discovered, but I guess thats a dwarf planet now and doesn't count.

Earliest man, I'm sure. The were named by ancient greeks. They did not realize earth was a planet - they thought earth was the center of the universe. They noticed 'stars' that changed positions, which were the planets, and they were the ones that names them planets, which is greek for "wandering star'.

The cave man. The human race has been watching this since the beginning of the human race. They noticed these bright spots in the sky did not go the same way as the other points of light in the sky over several weeks,

Mercury, Venus, Mars, Neptune and Saturn are all visible to the naked eye (no telescope needed) so the first to see the planets, as far as humans are concerned, was ancient man when he or she looked at the night sky.

Would be Copernicus.He was the first astromener to put the sun at the centre of the universe.Prior to Copernicus the scientists believed that the earth was the centre.This discovery also proved that the earth was a planet.As this was against church teaching,it was ridiculed by the church who warned against it's teaching
