irrefutable

ir-ih-FYOO-tuh-bul/ˌɪrɪˈfjuːtəbl/

Impossible to disprove or convincingly argue against.

The paint-covered hand against the fresh mark provides irrefutable evidence of contact.

Irrefutable evidence: a man's paint-covered hand is still pressed against a freshly marked white wall while another man points directly to the contact.
Etymology

Refutare meant both driving back and disproving: an argument could repel or overthrow a claim. Irrefutable describes a claim that cannot be defeated in this way; the use of refute for merely denying came later.
