Thank you for your comment.
Here is the link from a Greek newspaper, but I am sure Google translate will produce a decent translation. If not, tell me and I will translate it for you. I am pretty sure though that you will have no trouble finding the source article in English.
Seafaring at that time may not sound impressive to you, but we are talking about big distances. It is not just a couple of miles. And if it still does not sound impressive, then what Plato wrote about merchant ships travelling from all over the known world to Atlantis at 10.000 BC is perfectly reasonable, which was exactly my point in the first place.
I am not an expert, so I can not tell you for sure which human species it was that traveled to Crete. But suppose the article is wrong and those travelers were Neanderthals, as you claim. I do not see how that is less impressive.
The existence of those tools means that those people too existed on Crete. Unless you would argue that those tools were later carried to Crete by other people, which you have to admit that is a longshot.
