Sorry, haven't been around much lately. Between jobs and studying, I really have very little free time. And I'm spending most of that time playing Dishonored, which is turning out to be an excellent game.
Anyway, I have no reason to believe they are anything other than what astronomers claim they are. With that many methods, claiming they're wrong would be like ID'ers claiming that archaeologists are wrong about the ages of things.
With that said, I really have very little else to say about these planets. I'm not an astronomer, have never taken a course in astronomy (although I may have an opportunity next year), and don't really even see what the problem is.
