and i reiterate: irrelevant to the main issue at hand. i was making a point of adverse alien mindsets coloring their perspectives on the universe. but if you want to know why, i'll oblige.

nobody bothered to analyze keepers until chorban. still correct because if somebody did succeed earlier then we wouldn't have had to scan those 20 keepers. sure we hear and read bits and pieces about prior attempts to study the keepers and all of them ended in failure. failure to have something happen just means nobody bothered to try again and again. harder, more intelligently and covertly (because of the legislation) each time. "tried and failed" certainly does not count as success. hence, nobody -bothered-: they gave up.

why the failures? because of insufficient tech? we know chorban's scanning device is a "recent" breakthrough. what the f- have the other races been inventing for the past few millennia then? things that take care of more pressing issues, obviously. and when those are done they simply wrote off the keepers as not worthy of scientific curiosity, moved on with their lives.

as i said, the aliens -didn't- try hard enough. this is the long and short of it.
