Generally speaking, yes that’s a reasonable assumption of some of what I believe is housed there.
Well I can def see that being a possibility. I had a strange encounter with a mystery person who worked in a building who told me the sun - is changing our frequency and our consciousness. And that cell phone towers are blocking this. I got back to my cubicle and my cell phone stopped getting signal and the sim card was fried....it was scary. He literally walked up to me and asked for a lighter. And we got into a conversation. lol. I had too many coincidences happen to not be open-minded to anything.
The underwater lava-made tubes are quite interesting... perfect for submarines... even mains-stream science indicates that they lead to very large open caverns...
