Mmmmm, I've heard stories like this before and I definitely believe there are subterrainian cities going on. But I think it's a human thing and
it's being done as a pretty huge scale safeguard against the possibility of a global disaster.
I mean, it's true we don't know much about the layers of the Earth - they even thought it had a big hole down the centre of it at one stage - but I
just reckon this human project is going on and that's where these stories stem from. I find it far more likely that we at our stage can live without
direct sunlight because maybe it's being harnessed on ground level and being used underground to power synthetic lights and electricity etc.
So yeah, I think it's pretty likely - rumour is these cities are growing all the time and once you're in, you need never come out again. Sounds like
a bleak existence but then I guess you need never worry about the 100s of madmen who have access to the end of the world buttons.

oh it's funny
because it's true.
