Because Gliese 581 g, if it exists, is located near the middle of the habitable zone (or Goldilocks zone - [See related question]) of its parent star.
3-6. The 3 planet model would have gliese 581 b too hot, gliese 581 c in the habitable zone, and gliese 581 d too cold. The 6 planet model would have gliese 581 e, b, and c too hot, gliese 581 g and d in the habitable zone, and gliese 581 f too cold.
Gliese 581 g is located approximately 20 light years away from Earth in the constellation Libra.
The estimated temperature of Gliese 581 g is around -37 degrees Celsius (-35 degrees Fahrenheit). This temperature is an estimate based on the distance of the planet from its host star and its atmosphere composition.
Gliese 581 g is an exoplanet orbiting the star Gliese 581, located approximately 20.5 light years away in the constellation of Libra. It was believed to be in the habitable zone of its star where liquid water could exist on its surface, making it a potential candidate for hosting life. However, its existence has been debated and further observations are needed to confirm its properties.
The existence of Gliese 581 g, an exoplanet in the Gliese 581 system, is still a subject of debate among astronomers. Some studies have suggested its presence, while others have cast doubt on its existence due to methodological challenges associated with detecting such distant celestial bodies. Further research is needed to confirm the existence of Gliese 581 g definitively.
Goldilocks Zone or Goldilocks Planet.
Gliese 581 g was discovered on September 29, 2010.
No. g liese 581c is a planet that orbits a star, Gliese 581.

Gliese 581g lies in a zone called "the Goldilocks zone" or habitable zone [See related question]. It's an area in a planets orbit, where liquid water is likely to occur and thus harbour life. It's not too hot or too cold. (As in the porridge) It can also refer to a planet that is close to the size of the Earth.
Gliese 581 g is an exoplanet orbiting the star Gliese 581, located approximately 20.5 light years away in the constellation of Libra. It was believed to be in the habitable zone of its star where liquid water could exist on its surface, making it a potential candidate for hosting life. However, its existence has been debated and further observations are needed to confirm its properties.
It is a planet only about 3 times the mass of Earth orbiting in the habitable zone of the star Gliese 581. It is widely considered the most likely extrasolar planet to harbor life.

No. At 20.5 light years from Earth, and it only having been discovered, AND Terrans not having developed extra-light speed craft or wormhole technology, it would not be possible for anyone to have arrived at Gliese 581 G yet.
