evidenceless

Lacking any support

Evidenceless means lacking evidence or proof.

The word typically describes claims, assertions, or beliefs that have no supporting facts: an evidenceless accusation, evidenceless speculation about the cause of death.

It carries a dismissive tone—calling something evidenceless suggests it shouldn't be taken seriously.
