It's thick now. It's far from certain that it was thick to begin with.
Carbon dioxide may well have outgassed from rocks as the heat began to
build. In other words, it may have been a case of positive feedback.

It doesn't really matter where it came from, all that matters is that it's
there, and if you switch planets around you'll have to deal with it.
