While I wait

we could think like this

tunguska event of 1908 occurred because a foreign body came to close to gaia
when gaia felt the need gaias underworld telluric current instantly went out from gaias surface in a huge lightening bolt onto the incoming foreign body causing the foreign body to explode in the air and not hit the ground
thank goodness

telluric current called underground lightening is gaias guardian that is self organized by herself to be so

with that in mind someone or something constructing buildings utilizing shaped pieces of gaia called rock all over gaia into the function of which is the structuring of telluric current into a greatly enhanced protection grid of our planets surface is a clever idea

that clever idea was not ours its someones or something's clever idea that knows stuff useful to us living here

long and slow hot as well
