      Venus is nearly the same size as the Earth, and is often called Earths twin.
      Other than that we are now finding planets around other solar systems, and some of those are similar in size to Earth.
      So I’m pretty sure there must be other “Earths” out there almost the same as ours if we look long enough.

      Certainly! 😀 There are tons of galaxies with many billions of stars, so it’s definitely possible that there is another planet with features like Earth. The Sun is quite a typical ‘main sequence’ star, so there are lots that are similar.
