you mean to say, there is only one Earth planet in the entire Universe ? i doubt that too. even if there is no proof, it is just logical that each star has an Earth planet.

if our own Sun (a star) has planet Earth revolving around it, it is very possible that others stars have an Earth like planet revolving around them too.
