Our best shot at meeting time travellers is to found a religion. If time travel were invented today, trillions, even quadrillions, would be invested into visiting Jesus or Mohammad.

To really prime the pump, our Prophet should claim to have been visited by time travelers much as Mary or Mohammad were visited by angels.

You're missing a very simple explanation for why no time travelers: no means of creating time travel allows one to go back to a time before the time-travel device/system was created. What makes this plausible is that every speculative time-travel scheme yet proposed by physicists has had this feature. E.g., tachyons for communicating with the past using a "tachyon reflector" receding from us at either a great velocity or great distance, wormholes where one end has been accelerated to near-lightspeed and then returned, Tipler cylinders, etc.
