People were wondering why we don't have any information from Q about space, ETs, etc so that crumb was a good explanation. The "random" comment was great for plausible deniability.
All the autists talking about fringe topics are most likely incarnated ETs themselves - mostly from the Pleiadian, Arcturian and Sirian civilizations, that is why we have this inner curiosity that drives us towards these things. We lived on other worlds before, not just here on Earth. And that is completely normal.
Follow-up "are we alone" and "this is much bigger than even autists can imagine" crumbs only fit the bill.
