The nature of the universe precludes that we cannot ever have anything perfect, with the one exception being Jesus Christ. Therefore true loves have always existed, but there would ever be no way for them to meet. They would be always separated by time, and also geography, though the latter would not be as much of an issue nowadays. What was missing from the mix that brewed in the cosmos would always be a lack of circumstance.
If ever found, it would be generally considered as what the meaning of life has always been hyped up to be. And if you think we have found out what the meaning of life is, why do we keep asking? (Us, as a group, of earthlings.)
