Keep in mind that the human telepaths (as well as those of most races) were genetically modified by the Vorlons to have the ability to use telepathy. Also, the telepathy was certainly limited in range, never more than a few miles (and that was only with devices capable of enhancing the telepath's abilities).
Narf, look a bit harder to find some plausible scientific explanations for telepathy then. They are out there, somewhere. I did not say "proof", as that implies that telepathy actually exists. I said plausible explanations of how it could exist.
