Our problem is the number of people who have no basic concept of what evolution actually is.  The poster above, who answers a question on evolution with something about astrophysics instead of biology, is an excellent example of this ignorance.    A questioner yesterday asked nine questions about evolution, and only the last one actually had anything to do with evolution theory.  It's troubling to see this, especially when you see the same person make the same claims after having been corrected.
