No, it isn't.... a claim without proof is a falsehood.
Unless you mean a claim followed by "I have proof" is a false hood, perhaps.
But it is the claim of proof that would be the falsehood.
The sun is hot, I have proof.Person A: The sun isn't hot, I have proof.
Person B: What is your proof?
Person A: I cannot share this proof with you.
Person B: Then you're lying. Or delusional. One of the other. Or both.
What is your proof?
I cannot share the proof with you.
The sun is still hot....
