The first thought – is this a spoof? The second thought – why would people build tunnels?
At www.dailymail.co.uk/sciencetech/article-2022322/The-massive-European-net… … it seems by stone age they really mean Neolithic settlements (of early farmers) with evidence of tunnels, it is claimed, from Scotland to Anatolia (Turkey). We then learn the story comes from a book by a German archaeologist, Heinrich Kusch, 'Secrets of the Underground Door to an Ancient World' (or something like that). He suggests that as so many have survived this must imply there was an awful lot more of them in the past. That may be true – it may not be true. We then learn most of them are small and narrow affairs and designed to hide farm produce and items of value from unwelcome guests (or marauding bands). They don't appear to be refugia from invasions from the sky although it could be argued they could double up in that event. Meteors coming out of a clear blue sky are as quick as a flash so we can assume that humans were preventing other humans taking their hard earned produce. This idea is further supported by reason such tunnels tend to have areas where stuff can be stored (small galleries or rooms). They could also double down as somewhere to hide your women and children if hostile groups of people were in the vicinity. This appears to be the case with the elaborate underground tunnels and galleries in Anatolia – especially when foreign armies were running through eastern Anatolia (Cappadocia). You would have to read the book to find out what Heinrich Kusch has to say on the matter.
