It's pretty amazing just how ignorant, or maybe just stupid, people are. Here's a multi-year summary of a National Science foundation survey of several questions:

Europe in general isn't that far ahead of the USA in knowledge, either - see "International Comparisons" here:

Science magazine did a survey as well within the last couple of years.
