For any bit of evidence E0, you can always back it out based on E1,E2...

As P(E0|E1,E2,...)

Analysis starts in some context of belief. You can question bits of "evidence", and do a finer analysis, but the goal is usually to get a good answer, not reevaluate all your premises.

It seems like in order to go from P(H) to P(H|E) you have to become certain that E.

You need to be certain enough for the analysis at hand.
