Alternate Earth?

An artist's concept of a planetary lineup, featuring five exoplanets that may be similar to Earth: (L to R) Kepler-22b, Kepler-69c, Kepler-452b, Kepler-62f and Kepler-186f, with Earth on the far right. With more advanced telescopes, scientists may be able to find signs of life on exoplanets like these.

It's one of the more fascinating questions about space enthusiasts: Is there another Earth-like planet out there? The community has some theories:

There has to be some Earths floating around somewhere. Different Temp, different gravity, different color, etc. - natureday

YES AND NO: There are earths out there, but they aren't exactly earths. There are Earth-like planets, but they aren't exactly earths. Unless you think of alternate universes. Then there could be Earths - ThePatriotBeast

End of the universe vs. end of the afterlife.

Is SpaceX lying?
