If by earth, you mean the exact copy of this one, then probably not, but who knows, it happened here, so it may happen else where.
If you mean a planet with the right chemical composition to support life (as we know it). then this is far more probable.
We already are capable of finding planets orbiting other stars, and we have done, hundreds in fact, however, our technology is not sensitive enough to detect smaller planets like our earth size. But it wont be long, then the technology will be available to detect the light reflecting from these planets, and thus we will easily be able to analyse their atmospheric composition.
Just wait about a decade and I'm sure we will be far more knowledgeable on extra solar planets with suitable chemical compositions for life (as we know it)

Depends what you mean by "another Earth". It's unlikely that there's an exact copy out there - but I would imagine that there are other planets capable of supporting life in the way Earth does.

Why do you want for there to be another Earth out there somewhere in the Universe ? Why do the atheists want it too ?

What do you mean? another planet orbiting a star at approx. the same distance and with similar characteristics to the Earth? Almost certainly, given the huge number of ES planets.
If you mean an exact replica of our world, probably not!
(Reflect on how unlikely was your birth!)

It's very likely there are other earth-like planets out there, yes - although they wouldn't be exactly like our planet and if they were inhabited it's unlikely that it would be with the same animals that inhabit our world. So you couldn't really call it "another Earth", because this Earth is the only one exactly like this!

Not another exact copy of Earth, but probably a planet similar enough to Earth that we could live on it. Probably more than one. But we have yet to find it (them).

Yes - well at least there used to be one we knew about its called Mars, conditions there were just the same as on earth but the climates changed and it is as we see it now. Venus is behind us in the evolutionary scale but don't worry about the earth dieing cause only I will be here to see it - only the good die young

If you read Carl Sagan's first book (Cosmos?) he gives the probability of the number of earth like planets that should be there in all the galaxies and it runs into millions.

There has to be a life-bearing planet somewhere amongst the billions & billions of galaxies in the Universe! We can't be the only one.
