We started looking for planets that were in the life-supporting temperature range from their star, and have only recently begun looking at Earth-sized planets.

We started looking for planets that were in the life-supporting temperature range from their star, and have only recently begun looking at Earth-sized planets. There is an upper range to the gravity that we expect larger life to be able to form at, which means we have to limit the search somehow, to make a meaningful search.

I understand the we have to start somewhere. Agreed. I was questioning, out loud, if we are perhaps asking the wrong question. That's all :)
