Serious Question

What is the name of your state (only U.S. law)? Arizona
In the state of Arizona can a felony trial that has 2 class 2 felonies of a dangerous crime against children be heard that is strictly based on hearsay evidence and no DNA or physical proof? And if so how it is one persons word against another? Please help. Thank you for your time.

One person's word is not "hearsay" unless they are repeating what someone else told them. If that one person is a witness, then that person's testimony IS evidence. It would then be up to a court to weigh the credibility of the testimony (evidence) and determine if it is sufficient to overcome any reasonable doubt.
