You seem to be bothered by the scene enough to call him a pedophile, right?
My recycling of an old joke means I'm bothered? You either need to try harder or try something else, because trolling ain't for you.
We've already lost the details of history to time, not to mention equipment malfunction. Files are changed, translated and retranslated, rerecorded, lost, or outright reinterpreted. There are any number of reasons why the details could have been lost (on that particular planet!) with time, especially that far out in the future. Nothing indicates that we've lost the ability to write or type, or that all data was lost when the Crucible went off.
We've lost details from before the age of digital information. Losing the details of the Reaper war and Commander Shepard is an impossibility without a galaxy-wide dark age. And why, in an enlightened galaxy, would Shepard have become a Christ-like figure?
Yes, the galaxy went through a period without the relays, which limited their travel capabilities. Does that mean that being planet-locked was a universal situation for all time? Remember: one planet, one old man, one kid, and a lot of vagueness to adapt to all ending states.
It's not like that planet was forced on BioWare. They wrote that scene. It was entirely up to them to show what's happening long after Shepard fired the Crucible. Why would they choose some lone backwater that isn't indicative of what's actually happening?
It makes no sense. Apply a bit of logic instead of looking for the most convoluted answer.
