I haven't seen any larva tubes. I haven't seen anything that LOOKS like larva tubes. Larva tubes never have been known to meet at ninety degree angles. So we see that the thesis that we are seeing something that could throw immense light on our knowledge of geology is a good one and that therefore NASA is both remiss and clearly dysfunctional. Being a guardian against new knowledge and not a paid servant of science.
Yet still the very strangeness of these tubes, that look nothing like larva, are not the right size for larva, and have these bands that refute the idea of them being larva, also hold up the ancient lunar base thesis. Both good theses. Even the possibility of larva, though implausible, ought not be ruled out after all things may act differently with different gravitation, air pressure, and all that.
But both theses show that NASA is out of order and the mass-sackings ought begin.

Bear in mind that these banded covered roads (ie tubes that LOOK like banded covered roads) are 20-30 metres across. They are the size of roads.
Seriously I want to get rid of all voodoo from science. But I don't really see what the point is in pre-emptively ruling out ideas that there is no reason to rule out. That goes against the idea of following the evidence where-ever it leads you.
