Alpha centauri could host the closest Earth-like planet

I think that Alpha centauri could host the closest Earth-like planet.
 
A study shows that 22% of G and K-type stars could have Earth-like planets orbiting in the habitable zone.
 
There are 9 Sun-like stars within 25 light-years. If we make the calculation, two of those stars could have an Earth-like planet.
 
One of those two exoplanets could be Tau Ceti e. Which exoplanet could be the other one?
 
7 out of the 9 closest Sun-like stars have low metallicity. The only two stars with high metallicity are Alpha Centauri A and Delta Pavonis, but this star is suspected to be variable.
 
What do you guys think?

It's double.

Off to S&S you go!

Is there any long-term study of the ACen system of the types we have used for other systems to determine the planets there?

If not, why not? If so, what did they find?

Your reasoning is flawed.

Say - for the sake of argument - that 20% of men have green eyes. 

I have four male friends. They all have brown eyes. Therefore I must have green eyes?
