I'm not aware that any observer EVER argued that "all planets except Earth" orbited the Sun. The first person we know of to argue that the Sun was the center of things, and that the Earth orbited the Sun, was Aristarchus of Samos, a Greek astronomer and mathematician about 2400 years ago.
The idea that planets orbited the Sun had been thought of many times before, but it was not until the 17th century that this idea was actually supported by evidence from the first telescopic observations of Galileo Galilei.
Terrestrial planets are made of denser materials than Jovian planets. The planets were primarily formed from the left over disc of dust that orbited our sun when it first formed. The heavier elements were draw closer to the sun by gravity and the lighter ones flung further outward by their high orbital speed.
John Glenn orbited the earth, the first American to do so. He was forty at the time.

Yes, True
It was Johannes Kepler.
Johannes Kepler was the first to state that planets move in elliptical orbits.

No animal has orbited the moon other than man. Dogs and monkeys have orbited the earth.

ANSWER Sir Isak Newton was the first person to realise that the force of gravity was universal. It is Kepler motion that describes the elliptically orbits of the planets.

He first suggested that the Earth (and the other planets that were then known) rotated around the Sun instead of the other way around.
