    I have heard it theorized that because the universe is so overwhelming massive, that it is possible that the exact conditions found here could be repeated elsewhere, leading to mirror Earths or what we would dub as alternate versions.

    One, each planet is unique, but there may be some others very much like Earth.

    Even if there is only 1-planet Earth in every galaxy, 

    then there are trillions of them out there.

    Perhaps none. [Other than the one we know of - of course] Or maybe so many it would be impossible to count. I have often thought it possible for many 'earths' to exist. Sometimes with completely different people. And sometimes with carbon copies of us - with different lives. And each carbon copy [looks wise and personality wise] is subjected to a different set of circumstances to see how 'we' would react. With a great imagination the possibilities are limitless.

    Since, as far as we know, the universe is infinite there will be an infinite number of Earthlike planets. Locating them is another matter of course.

    Precisely like Earth, only our one.

    IF you loosen up the criteria, we might find some similar but in all likelihood, we'd have to terraform the planet with our natural partners like bacteria, fish, plants, etc., then there could be 100,000 planets or more.

    Then the only issue is getting there, takes about 50,000 years (!!!!!) to get there.
