[r0muald]

But there have been morals for a long time.

So either humankind is part of nature, and then it's safe to conclude that nature has morals (no matter how little right now, it's certainly part of humankind), or we're out of nature and there's no advantage in pointing out that nature has no morals.

Or there have been claims of morals for a long time. As in, "what serves my interests is moral".
