Must Be Yet Another Example

I object to the term 'Earth-like'. Ok, the planet has rock and metal. But it is twice as dense as Earth and has a surface temp probably hot enough to melt steel. It is extremely unlikely to contain water in appreciable, usable amounts and probably has no atmosphere to speak of (at least not a nitrogen/oxygen atmosphere).

Where does the 'Earth-like' bit come in??

'Galaxy-like" should be the claim, since everything is composed of nearly the same elements in varying proportions. You may as well call space aliens "human-like".
