You can. That's sort of the point. The "facts" you speak of in TES are also often contradictory and that is by design. Historical "facts" in the game world are just as "factual" as those in our real world. Which is to say that the facts are governed by the political climate and the whims of the ruling parties. Talos was 100% without-a-doubt ascended to Godhood... until the Thalmor told us that he wasn't. Now who you believe in that battle is up to you, but if Bethesda decided that the Thalmor were right that would contradict much of what was said about Him prior to Skyrim.

There are books in Morrowind that contradict each other. Not a mistake... this was done on purpose.

So as for what Bethesda tells us is fact.... there aren't many big pieces of the story for which we can say for certain are absolutely true.
