How, may I ask, do you know that no one on Earth has previously accessed information about the under-underworld (or the sub-sub conscious)?
You may always ask.
Firstly, there is ever less knowing.
Secondly, when I went down to the under-underworld, the gates were locked. No one had ever gone in (and come out again). This would absolutely not be the case if someone had accessed it before – or was even aware of it.
Thirdly, I confirmed this with the angel god who was in the hospital helping me come back from the coma (the descent). Angels don’t know everything – particularly when it involves something analytical. But they cannot give inaccurate information; instead they’ll say they don’t know. An angel wouldn’t know the answer to such a big question, but an angel god would.
