There is a philosophical insight by an ancient Greek sage named Heraclitus which described a common truth awareness existing in the Universe that is manifest to each of us as a flash inspirational realisation of background truth from time to time that can be transitory in our minds then disappear like a forgotten dream as our thoughts take over - he called it the Logos. Later it was compared to something like a ledger of the universe - a tangible existence of common truth. We could nowadays call it objective truth. Later after Jesus of Nazareth appeared preaching in Galilee and Judea the disciple John seems to have identified Jesus as the physical incarnation in flesh of the Logos. So it seems that irrespective of whether people exist who know a truth, it is still true - because one being always exists who knows all things who strangely enough has created a person in which to embody all He knows - the Logos. Stranger still is that this Logos came in the flesh as Jesus of Nazareth.
