It's regarding the research of a man who had come to pretty interesting conclusions, and I do see a connection with the Dulce Base, or Orion/Reptilian research on Farsight.
He claimed to have been able to apply context based cryptoanalysis and captured databurst messages in the Ghz frequency.

You tell me if you think those messages as reassuring or disturbing, here are few translations of the American Military "ET Partners"

"GROUND.
GROUND. WOMEN OF EARTH
ARE NEEDED. FLEXIBLE THE NEXT
DISCHARGES OUR SHIP ALL WOMEN. DO
NOT COMMAND THE NORTH AMONG US.
YOU HAVE MANY FRIENDS. WATER VERY
SHORT. RESIST ALL ATTEMPTS AT ALTERATION.
LISTEN. ORANGE.

MAKE PEACE. "

"VICTORY. OUR BASES OBTAIN
SUPPLIES FROM THE STARSHIP
METAL.
TIME IS YANKED. TIME IS YANKED. MESSAGE HIT STAR.
USING REJUVENATIOW METHODS
GOT US IN TROUBLE. SIX SKY WE
REALIZE TELLING YOU ALL MIGHT
HELP YOU. "

This message is very nice and innocent as well

""TAKE VAST PORTION UNIVERSE
AGAINST OUR AGGRESSION.
THE NUMBER OF OUR CRASHED
SAUCERS IS EIGHT.
NERVE YOU WE REALIZE TELL
THE TRUTH. JUMP. JUMP OPPOSITE.
ALIEN FORCES MEAN NO HELP TO
YOU. METAL WE COME INVISIBLE.
KEEPING CHANGE WE WILL NOT
JOIN SIDES WITH ANYONE. OUGHT
OUR RACE IS DYING ON THE HOME"

Just an impression, but seems that they are pretty busy:
1. Taking vast portions of the universe
2. Dumping large quantities of women into a starship, unalterated so perhaps that means "alive"

Contextual clarification, Betelgeuse star in the Orion constellation, according to our astronomers will go supernova shortly which means everything in a distance of 50 light-years around the star will be destroyed.
That can explain the reason why they say ; "Our world is dying"
They are desperate to find a new place, preferably a nice one with different climates with resources available, ideally with a slave population waiting just to be enslaved
