The internet is terrific

I see the internet as being quite possibly the greatest research tool ever invented, but then again, at other times what can be found out there just helps strip away hopes and dreams for the future of mankind.
While browsing randomly I came across this little nugget of brilliance (see the first post in this link):

http://www.gaiaonline.com/forum/morality-and-religion/evloution-and-science/t.39496627/

I'll even quote it here for simplicity:

"For those of you who believe in evolution, how does it explain gravity? The theory of relativity? The planets? The solar system? Oh and this time guys...try putting references in your replies...no references, no replies."

I understand the fact that different people possess different levels of personal knowledge, but honestly; how can anyone be this ignorant of the theories of evolution, relativity and stellar dynamics in this day and age? This person effectively rapes fifth-grade science and has the gall to demand references while not providing some herself. And while I know it is tempting to call Poe's law on this one, I doubt it would be correct after reading the quoted thread in it's entirety.
