When you make a claim, generally you need to back it up with some evidence, otherwise you seem like you are mistaken or dishonest.
You tried to provide proof, so you obviously have some understating of this, but your proof was faulty, so your claim is probably going to be considered to be "unsubstituted", or just untrue.
It's OK. This type of thing happens. No one is going to hold it against you or think less of you. It's just your claim is likely not believed.
