What is Imam Malik's evidence that God exists?

Ibn Kathir narrated that Imam Malik used the argument of different languages and voices. He said:  وَحَكَى الرَّازِي عَنِ الِإمَامِ مَالِكٍ أَنَّ الَّرَّشِيدَ سَأَلَهُ عَنْ ذَلِكَ فَاسْتَدَلَّ لَهُ بِاخْتِلَافِ الُّْلَغَاتِ وَالأَصْوَاتِ وَالنَّغَمَاتِ "Razi narrated that a man called Rashid asked Imam Malik about this (evidences of the existence of God) and he argued (the evidence is) 'the different languages, voices and tones.'" (Tafsir ibn Kathir, Vol. 1, p. 58) Imam Malik argues such complexity and abnormality requires a designer. The basis for this argument is as follows:  All human societies have language, and as far as we know they always have. Language does not appear to be invented by some groups and spreading to others like we see with agriculture or the alphabet. The grammars used in industrial societies remain no more complex than those of hunter-gatherers. Humans are proficient language users regardless of intelligence, social status or level of education. Therefore, God exists, endowed humans with an innate ability to acquire and use language. The Biochemist Michael Denton says:  "The origin of language remains an abiding mystery..."
