before we could actually see what planets were out there, we were guessing and as it turns out a lot of our guesses were wrong.

We thought planets wouldn't form around low metal stars and now we find planets around such stars.

we thought planets would have trouble forming around binary systems and now we find planets with multiple suns. I think the record is four.

until we get hard data, we are just guessing.
