My impression is that their reasons for dating it so old are very shaky. Basically they tried to find a match between the stones and some stars and by looking hard enough, they found one by coincidence.
The only real way to date such a site is if the builders used wood, then carbon dating can be used, or if they left tools lying around that would be a good indication of the period.
Here is someone who went into it in more detail:
He says that archeologists believe the stone structures in the region were made by the Bantu who got there about 1800 years ago, so any time after that.
He also reckons the claimed alignments are just made up.
