Addressing the second paragraph here - while conflation and reconsolidation are real phenomena, it's also quite clear that most humans form episodic memories. Some quite clearly have incredible abilities in this regard [2]. A distinction between semantic (facts/concepts) and episodic (specific experiences) declarative memories are fairly well established since at least the 1970s. That the latter is required to construct the former is also long posited, with reasonable evidence [1]. Similarly, there's a slightly more recent distinction between "recollecting" (i.e., similar to the author's "I can remember the event of learning this") and "knowing" (i.e., "I know this but don't remember why"), with differences in hypothesized recall mechanisms [3].
