(Az-Zukhuruf) 43 : 84

وَهُوَ الَّذِي فِي السَّمَاءِ إِلَٰهٌ وَفِي الْأَرْضِ إِلَٰهٌ ۚ وَهُوَ الْحَكِيمُ الْعَلِيمُ

And He is the only "Ilah"-Deity- in heaven and the only Deity on the earth; and He is the Wise, the Knower.

To understand about the Deity, read the explanation of the verse 2: 255. Allah is the single Deity not only on the earth, but also on any planet in the universe. See explanation 23: 116–117; 28: 88; and 41: 5–7.
