The odds are ...

As tech gets better, more planets like earth will be found without issue ...

To be considered Earth-like, a planet must be similar in size to our planet, orbit a sun-like star called a G-type star and be a rocky or terrestrial planet. And, naturally, it needs to orbit in the habitable zone of its star. This is the distance where the planet is just the right temperature, not too hot or too cold, to host liquid water, and potentially life, on its surface.

But some of these unique characteristics also make them harder to find in the search for exoplanets because they're small and distant from their stars.

However, astronomers at the University of British Columbia have discovered that there may be as many as 6 billion Earth-like planets across our galaxy. That means that there could be one Earth-like planet for every five sun-like stars in the galaxy.

Seems scientists have one candidate in hand ...

Some 3,000 light years away from Earth, researchers believe they have found an Earth-size exoplanet orbiting a sun-like star.

The star is known as Kepler-160, and it was observed during NASA's exoplanet-hunting Kepler mission between 2009 and 2013. It's similar in size and temperature to our sun.

The planet candidate has been dubbed KOI-456.04. It is less than twice the size of Earth and receives a similar amount and type of light from its sun-like star.

The planet candidate is also orbiting at a distance that places it within the habitable zone of the star, where the surface temperature of the planet could support liquid water — and the potential for life. That's similar to where Earth sits in relation to the sun.

And it has an orbital period around the star of 378 days, similar to the Earth year it takes to complete an orbit around the sun.

The odds are ... looking pretty good are they not? :)
