Hello! Could you please tell me which one is grammatically correct? I think #1 is correct.
#1There're many animals on the Earth.
#2 There're many animals on the earth.
And I think I should capitalize "Sun" and put "the" before it. Am I right?
By the way, are those grammatical questions? I think yes.
I would say it depends on the importance that you give to that Earth. Eg I am used to seing written 'Earth' when someone is talking about our planet, Earth.
By the way, I have just looked it up and it seems we have got to type 'Earth'.
Not a teacher at all, anyway
