Theoretical: virtual photons

Casimir effect proved that virtual particles exist... can we not deduce that (now we have the Casimir effect, on top of the maths side) that virtual photons exist too?

Gluons are experimentally proven by the way, as are virtual particles (as 5614 said).

True, (for some reason) I thought the OP wanted particles that weren't directly observed.

Hardly any fundamental particles are directly observed. What does 'directly observed' even mean? I suppose the only particle you ever really directly observe is the photon....
