Because nothing else has the energy required to boost things into orbit in the time that they do. Other fuel/oxidizer combinations such as kerosene and liquid oxygen, burn more slowly. It's difficult, but it can be calculated by timing how long it takes them to get to a specified altitude, and prove that it is hydrogen and liquid oxygen. Nothing else will work that fast. It's verifiable.

In science, honesty is very important. That is why when there is a lack of it, there are big problems which arise. NASA is scientific in scope, it would be bad ethics to be anything but honest, and very bad science as well.
The answers above give you great reasons why they use what they use, NASA doesn't work on deception but the scientific principals those answers imply.If you don't trust the scientific sources that tell you what they are discovering about something so simple as what they use for equipment, then surely you must be growing to doubt their results, and no serious scientist ever wants their work to be doubted for its worth, though they do always want it tested and verified and thus doubted in a different manner (not is it real but is rather is it correct)

Because liquid oxygen and hydrogen is very efficient, if you test the fuel you'll confirm that it's liquid oxygen and hydrogen. They're VERY combustible.

Are you afraid they are using something more harmful or potentially harmful? i.e. Nuclear fueled.
Keep in mind that they are a highly scrutinized agency.
