Earth. Earth was the 1st Earth-like planet that was discovered.
So far, no extra-solar planets that could claim to be "earth-like" have been discovered. However, this isn't at all surprising; our technology is barely able to detect planets of ANY size orbiting other stars, and Earth isn't all that big. (Although it does seem to be just right for US.) With the development of newer instruments, especially the James Webb Space Telescope scheduled for launch in a few years, our chances of finding a suitable planet will be greatly improved.
All that will be left will be to complete the design of the ORION rocket, and launch it full of adventurous colonists on the chance that it would be habitable. We really do need a second home for humanity among the stars!
