Ok, but that's not really the point. If I change it to "have everybody you know and came in contact with make the list". Then, from what I can tell, THAT satisfies your argument.
And, if one had enough outside contact, one could still reconstruct most of the events of the day. And, with each successive bit of input - friends, surveillance cameras, fast-food cashiers, the events of the day would become much clearer.
Some of the "missing links" may never be known - nobody saw you - maybe you were alone.
But, then start examining changes in the house, phone bills, TV audit trails, food in the fridge - and, in many cases , a pretty darn clear picture of "what you did that day" would emerge. And, the Fast food person may remember you - but not have a clue as to what time of day it was - but, based upon the timeline of other obersvations - one might be able to infer WHERE in the timeline the visit to Burger King took place.
And, my point is, just because there is nothing to pinpoint exactly what you did at say between 6AM & 7AM, it does not invalidate the the rest of the information.
Police do this sort of investigative work all the time.
That's all a "missing link" is. One more piece of a puzzle in which you will NEVER have all of the pieces.
"Some of the "missing links" may never be known - nobody saw you - maybe you were alone. "
Yeah, that's the point. You don't really know if two fossils are related without all of the links in between.
How do you know two things are related if there are huge gaps in between? The answer is that you can't know for certain, but we are told by archaeologists all the time that one animal is descended from another -- without sufficient evidence.
It's all based on assumptions and suppositions. Apparently as long as I can imagine something a certain way that's all the data that's needed.
