There's a Portuguese saying "há mouro na costa" which is literally "there are moor at the coast" and means that there is something fishy going on.

[Al-Khwarizmi]

Curious, in Spanish we have the same saying, but always in the negative version ("no hay moros en la costa") which is something you say when you're doing something secret and there is no one around who could see, hear or cause trouble.

In the UK we say 'the coast is clear' when telling someone that 'there is no-one around to see any misdeeds you're about to do'. Nothing about Moors, nor even Spaniards!

The Moors existed about 1900 years after the Sea People of the Bronze Age.

I don’t think they’re implying the moors are responsible for the Bronze Age collapse, merely drawing parallels.
