Unfortunately, a lot of science is like this.
Certain topics are "impossible" and never investigated.
After a contact at Harvard shot me a report into the 2004 Nimitz
incident, and I discovered another report into Mainbrace in the 1950s
that seemed to be much the same thing, I had to start looking at
the actual data.
And, unfortunately for many TV scientists that laught out loud
at the thought of "aliens", there is far too much data pointing in
the same direction to be easily ignored.
Even the craziest conspiracy theories you have ever heard
about UFO's have *some* hard evidence backing them up.
As far covid being something introduced from outside the earth -- yes,
there is some evidence for that. It seems the "pulses" or "surges"
we have seen world-wide, many of them seemingly starting on the same
say in widley-separated countries that supposedly have closed or
restricted border entry procedures, seem to coincide with close
approaches of Mercury which everyone on this group should know happen
every from 90 to 110 days depending on the relevant positions.
Mercury having that huge eccentricity and all.
It is conceivable that new viral variants are arriving on earth
via some planet via an orbital gravity assist from Mercury.
You might do it that way because (a) you hate earthlings for their
damn interfering with basic food sources you've been farming for
centuries, (b) your home planet/moon is not always in a great
position to dump sh*t on them, (c) it throws off earth authorities
who can barely add 2 numbers together anyway, and figuring out
who is doing what will be almost impossible for them.
Still, no evidence I know of shows more than just the possibility of
the idea at the moment. But you never know. The Pentagon now admits
it has been lying about UFO's for the past 70+ years -- maybe they
know what is going on and just dont want civilization or oil prices
to collapse if we find out there are critters or some long lost
earth civilization operating out there somewhere.
