In many languages, the name for Earth is basically "land", more in the literal sense of dry land (instead of a political division, like "country"). Even now in English, Earth is both a term for soil, and the name of the planet we live on. Same in Spanish: tierra, Earth, land, and soil.
Long before people knew the Earth was a sphere, many people basically thought that the entire universe was basically divided into three parts: land, sky, and ocean. (Stars and space, what we think of today as most of the universe, were though to be much smaller than they actually are, and were part of the sky, which was a dome).
It was only later they put it together that the "sky" was actually much bigger, and in fact an optical illusion-- it actually isn't a blue dome, even though it appears to be. Also, the water and land aren't co-equal parts; the water, though expansive, is a relatively shallow cover over some parts of a large rocky planet.
Even though we learned all of this, we still kept the same basic name that we had long before this understanding. We live on the land, the soil-- the Earth.
So look at another language, Finnish, a non-Indo European language. Earth, the globe, is maapallo, which is made up of two words: maa, earth, land, soil, and pallo, ball or globe. So the Finnish word for the planet Earth can be translated as "land-globe" or "soil-ball".
I would say that aliens probably name their planet on whatever material they live on. A dolphin like species would probably call their homeworld "water" or "ocean". Beings that evolved on a gas giant would probably call their home the gas-liquid that they live on.
