Try to the phrase the X with very specific verifiable empirical evidence.

It's a bit ridiculous to make a claim of truth for an entire volume of information. Scientists, for example, don't do this. There are always going to be errors that creep into work. Einstein's has a paper called "Relativity: The Special and the General Theory." Scientists don't say "I would not believe in relativity if Einstein's paper were not true." They give specific evidence. For example, they would say they don't believe in relativity if light from stars didn't bend around the sun. Try something like that.
