I'm 18 and my girlfriend is 15, could I go to jail if someone other than her claimed statutory rape? My dad says I would have to prove that we didn't do anything and I say the law would have to prove we did. Who is correct?

Please read the laws carefully. I have highlighted the pertinent points. There is not much evidence required to be charged with this crime.
