Alexander Knörr is the author of Hagar Qim  in which he discusses the cart-ruts of Malta, concluding that they must be at least 9,000 years old. But he goes further, declaring that the famous temples of Malta are more than 12,000 years old!
>Knörr has published, in German, a wide selection of both fiction and non-fiction books(b).< Inevitably, he tackles Atlantis, attributing its demise to the breaching of a dam at Gibraltar leaving Atlantis at the bottom of the Mediterranean.>However he offers little evidence to support his wild speculations.<
Nevertheless, Roland M. Horn has offered a favourable review of Knörr’s book(a).
