Here. But now this:

It is most likely that we are the only living beings in our galaxy, according to an esteemed former Nasa scientist. William Borucki, who played a large part in finding other potentially hospitable planets during his role as chief investigator for the US space agency’s Kepler mission until his retirement in 2015, said that the evidence points to us being alone, in our galaxy at least.

Definitely don’t blast off just yet.

I believe Borucki's argument is that we would have heard something if an intelligent civilization was within our galaxy. It has nothing to do with the rareness of Earth or its properties. In fact he seems to imply that Earth is not rare at all. This is the first time recently that someone is apparently saying that Earth is not rare. Of course there is no close up evidence of just what any other planet is about. But on the same page there is an article about a newly discovered planet. http://www.ibtimes.co.uk/earth-2-0-nasa-announces-discovery-new-planet-substantial-opportunity-alien-life-1512297
The planet, called Kepler 452b, is described as a "bigger, older cousin" to our own planet and is the smallest planet so far that orbits in a habitable zone around a star similar to the Sun. The planet is 60% larger than Earth, and its orbit is only 20 days longer than our planet's. Scientists believe that its 6 billion years in the "habitable zone" near the star, which has a similar mass and temperature to the Sun, is more than enough time for life to have evolved in its oceans or on its surfaces.
But Eric Metaxas indicates that any planet varying just a small amount from Earth would not be habitable in any way we know. jerry
