Life around tau ceti

Does anybody think that there could be any life on planets or moons around Tau Ceti? Why or why not? If so, how advanced? Kardashev 0, 1, 2,3? Or Higher? If not, how about in the past could there have been life on planets or moons around Tau Ceti? Besides the fact that there would be 10 times more cometary bombardment on these planets, is there any other details that would make life possible or impossible? Please give suggestions. Thank You.

I'M LIKE YOU I BELIEVE THAT THERE'S LIFE OUT THERE, I DON'T BELIEVE THAT IS ONLY JUST EARTH, COME ON THOSE PLANETS AREN'T OUT THERE FOR NO REASON, IS JUST PLAIN AMAZING, MY FAVOTITE WOULD BE SATURN, ISN'T THAT A BEAUTIFUL PLANET? I want to BUY CUT OUTS WITH THE PLANETS FOR MY KIDS ROOM BUT I DON'T KNOW WERE TO FIND IT.
