A paper without any citations is generally considered such a bad source that it's only one step up from wikipedia. You can cite it, if you must, but you better not base your research on it.

If this were true how would anyone ever get the first citation?

(Incidentally in my own field, there are a lot of papers that don't get cited. It isn't because the papers are wrong (although some very small fraction of them have that problem) but that they just aren't interesting. But math is very different from most other fields.)
