Thargoids knows that one human does not speak for the entire hive. It is not logical to them, but I think they have accepted it.
This is how we greeted them the first time thy dropped by:
'THE THARGOIDS - TRUTH AND FICTION -11
M.C.S
The Thargoids were first reported in human space by Lens Nikon, supervisor of the 'Planets Unlimited' Terra-formation Project on New Africa (Veliaze -2,3). They appeared in large numbers following the initial stages of planetary alteration. Initially only the Thargons were seen, flying in linear formation at a steady distance from the Planets Unlimited fleet.
It was only after the instigation of oxygenation that a mother ship was observed from a distance and no hostile action was reported until one of the Fleet Commanders ordered his defence wing to "melt them down".
There followed the complete destruction of all Thargoid ships in the area, including the mother ship. Forty eight hours later, the entire Planets Unlimited Fleet experienced a mis-jump and were met by around thirty Thargoid mother ships with an encircling fleet of Thargons.
Only two survivors returned (both unscathed) and neither made coherent reports although it seems likely that the two may be the only humanoids to have seen a living Thargoid and survived. Reports of their debriefing at the Therapy Centre on Eta Cassiopoea, suggest that the Thargoids made several attempts to open negotiations but were fired on at each juncture.
The exact details will never be known but the first shots were undoubtedly fired and the Thargoid Wars started in earnest. Hostilities continued for the next century and a half with neither side making sane communication with the other.
Or did they?
In our next report, we examine the issue of Inter-Species Communication.'
We could perhaps try something different with the next species we bump into?
Lens Nikon - I have a good laugh every time I see that. "I'm stuck for a name... <looksAroundOffice>...yeah, OK, that'll do."
