No one person named it. People spoke of “the earth,” meaning the ground, back when they thought the sun moved around it. When the earth was found to be just another planet, it was still the earth. Not very imaginative, but very functional.
Nobody knows when people started using words like "Earth" or "Erde" to refer to the planet as a whole and not just the ground they walked on. Back in 1783, German astronomer Johann Elert Bode named the seventh planet from our sun "Uranus" (after a Greek god).
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words 'eor(th)e' and 'ertha'.
It is a common misconception that “Terra” is the internationally-recognized scientific name of the planet, but in reality Earth does not have an official international name. The standard English name of the planet, including in science, is “Earth”.
Earth's name is Gaia, which has recently been revived (thanks, largely, to Lovelock's "Gaia Hypothesis").
For example, the modern English word 'Earth' derives from the Germanic 'erde', meaning 'ground'. The roots of such words all date from a time when humankind was unaware that Earth is actually a planet. They merely signified the ground beneath our feet, and were adopted for the planet later on.
But what caused Earth to tilt? Long, long ago, when Earth was young, it is thought that something big hit Earth and knocked it off-kilter. So instead of rotating with its axis straight up and down, it leans over a bit. By the way, that big thing that hit Earth is called Theia.
However, the common thread in all languages is that they were all derived from the same meaning in their origins, which is ' ground' or 'soil'. The modern English word and name for our planet 'Earth', is said to go back at least 1,000 years.
Roman mythology is to thank for the monikers of most of the eight planets in the solar system. The Romans bestowed the names of gods and goddesses on the five planets that could be seen in the night sky with the naked eye.
In ancient Roman religion and mythology, Tellus Mater or Terra Mater ("Mother Earth") is the personification of the Earth. Although Tellus and Terra are hardly distinguishable during the Imperial era, Tellus was the name of the original earth goddess in the religious practices of the Republic or earlier.
Most likely Earth was not named after a Greco-Roman god because it was not recognized as a planet in antiquity. The word planet means wanderer and the name Earth comes from the German word Erda and the Old English derivative of Erda, Ertha. In both languages it means ground. The ground doesn't wander.
This giant landmass known as a supercontinent was called Pangea. The word Pangaea means "All Lands", this describes the way all the continents were joined up together. Pangea existed 240 million years ago and about 200 millions years ago it began to break apart.
in greek - Gaia , this was the name of earth in their language. In Summerian (dated to around 2900 BCE) earth is known as KI or GI. in Egyptian ( 2700 BCE) earth is known as Geb or Keb . in Anglophone countries , it is known as Tierra, Monde and Erde.
Earth is Old English and German in origin, related to the Old Saxon 'ertha', the Dutch 'aerde', and the German 'erda'. Terra is a French and Latin word, and so isn't part of the 'Earth' etymology.
Earth is 地球 Dìqiú, lit. global land! 地dì：land, soil, fields. 球 qiú：ball.
Pangea, also spelled Pangaea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth. Pangea was surrounded by a global ocean called Panthalassa, and it was fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago).
When you are talking about the ground or soil as a surface or stratum, then you must lowercase the word: The archaeologists excavated the earth at the site. It is acceptable to leave earth lowercase and use the with earth if you are talking about it as the planet we live on: The earth rotates on its axis.

Earth is the only planet not named after a Roman god or goddess, but it is associated with the goddess Terra Mater (Gaea to the Greeks). In mythology, she was the first goddess on Earth and the mother of Uranus. The name Earth comes from Old English and Germanic.
(Uranus is also the only planet to be named after a Greek god rather than a Roman one.)
Adamah (Biblical Hebrew : אדמה) is a word, translatable as ground or earth, which occurs in the Genesis creation narrative.
In Greek mythology, Gaia (/ˈɡeɪə, ˈɡaɪə/; from Ancient Greek Γαῖα, a poetical form of Γῆ Gē, 'land' or 'earth'), also spelled Gaea /ˈdʒiːə/, is the personification of the Earth and one of the Greek primordial deities. Gaia is the ancestral mother—sometimes parthenogenic—of all life.
Prithvi or Prithvi Mata (Sanskrit: पृथ्वी, pṛthvī, also पृथिवी, pṛthivī, "the Vast One") is the Sanskrit name for the earth, as well as the name of a devi (goddess) in Hinduism and some branches of Buddhism. In the Vedas, her consort is Dyaus Pita, the sky god.
Jupiter formed less than 3 million years after the birth of the solar system, making it the eldest planet. Saturn formed shortly after, amassing less material since Jupiter gobbled such a large portion of the outer disk.
