Which pronoun shall be used for nothing in the sentence: it or they/them

Question

I wonder which pronoun this sentence takes.

Nothing belongs to you on the planet, but you can make use of it/them.

Answer 1

Nothing is comprised of no and thing. Just like 'another' that is 'an other' something. Broadly they are singular. That's why we say - Nothing is permanent.

So, in the given sentence, it smoothly goes with it.

But note that you can write it in better way. Also, it'd avoid the complexity.

You own nothing on this earth, but you can use everything.
