Exactly correct.

Occam’s razor:
In its simplest form, Occam's razor states that explanations should never multiply causes without necessity. When two explanations are offered for a phenomenon, the simplest full explanation is preferable. If a charred tree is on the ground, it could be because of a lightning strike or because of a secret government weapons program. The simplest explanation that is sufficient is the logical one, according to Occam's razor, and there was a lightning strike.

"Occam’s razor"

In simpler terms: "When you hear the thunder of hoof beats, look for horses, not zebras."

P.S. Particularly in the good old U.S. of A.
