Thinking, why would they go through the trouble, the time, money and energy to build tunnels that had arbitrary endpoints?
They did go about their business in a most structured way.
So, what about Obelisks, like The Washington Monument?
2 Chron 31-1 "Now when all of this was finished, all Israel who were present went out to the cities of Judah, and smashed the [pagan] pillars (obelisks, memorial stones) in pieces, cut down the Asherim (wooden symbols of a female deity), and tore down the high places and the altars [of idolatry] throughout all Judah and Benjamin, as well as in Ephraim and Manasseh, until they had destroyed them all. Then all the sons (descendants) of Israel returned to their own cities, each to his own property."

They are demons and their whole system is set up for trafficking and tunnels. Fiat itself is death and trafficking increments, a way to steal our time, and fiat launder. Ultimately their whole satanic matrix is set up with this in mind.
