Dating proto-languages is obviously something we can't do precisely, but we can offer reasonable ranges. For example, Proto-Indo-European can't really be much younger than 5 millennia, and let's say that 9 is an upper bound that would satisfy even the Indo-Anatolian and Anatolian Urhemeit proponents.
For Proto-Afrasian, Wikipedia gives an incredibly wide range of 7500 BC - 16000 BC, with dates before 10000 BC seemingly contested by lexical evidence. In any case, this is certainly older than PIE. Among generally accepted and proven language families (eg. not anything strictly containing Indo-European) what are the others with a remarkable time depth? Are there any which are possibly as deep or even deeper than Afrasian?
