If the planets exist, they orbit a star about twice as old as our own, so a suitable planet has had plenty of time to develop life much more advanced than Homo sapiens. That may just explain why no one from Tau Ceti has ever contacted beings as primitive as us.

"ASTRONOMERS have discovered what may be five planets orbiting Tau Ceti, the closest single star beyond our solar system, the temperature and luminosity of which nearly match the sun's. If they are planets, one is about the right distance from the star to feature mild temperatures, oceans of water, and even life. Don't pack your bags just yet, though: the discovery still needs to be confirmed."
