It's really not "perfectly" explainable by physics since we don't understand all aspects of physics yet. If you said "mostly" explainable by physics I would believe you.

Also, if an alien happens to be shining a beam at us rhythmically, that's also "explained" by physics but we won't actually know if the source is a natural phenomena or an alien shining his super flashlight at us.

No, that was the right phrasing. It isn’t perfectly explained, but its perfectly explainable.

It is not perfectly explainable by us, though.

And it may not actually perfectly explainable ever. Nothing guarantees we can get a perfect understanding of physics.
