Irrefutable

Irrefutable!.

Context: "A Large, Complex, Detailed but irrefutable REPORT on the Presidential Election Fraud which took place in Georgia is almost complete & will be presented by me at a major News Conference at 11:00 A.M. on Monday of next week in Bedminster, New Jersey..." —Donald Trump, via Truth Social

I'll bet the report is carved into a solid block of pure irrefutium using a stainless unobtanium chisel.
