"…no signs of extraterrestrial beings were found."
"It is suspected that unmanned warships and drones were controlled by artificial intelligence programs."
"However, no traces of any programs have been found on the three captured warships, nor is there any computational carrier for such programs."
"Of course, this might also be due to the difference in technological levels and the disparity between civilizations. There are several conjectures, one, the aliens were gaseous lifeforms that would immediately decompose into certain gaseous components upon death."
"Two, were the aliens some kind of energy beings?"
"Three, could it be that the alien's program carriers are not computer-like devices, but rather energy-based logic programs?"
Eight days after the battle, the three alien warships had been completely disarmed, and to absolutely ensure safety, all energy circuits on board were cut off, leaving the three vessels as mere ornaments in the Moon's orbit.
