That because those are virtually the only folks nowadays who are questioning the theory of evolution.
Oh, how you wish that was true.
But you can hear the footsteps, can't you, Coyote?
More and more scientists, with better and better qualifications, questioning the theory. More and more people breathing on your fragile little house of cards. More and more hitherto sacred absurdities being exposed by mathematics and observed data. More and more intricacies of DNA being uncovered by the year, consigning your theory firmly into a place of academic fantasy.
To the point where an American President would consider it appropriate to promote the principle of ID.
Listen to those footsteps, Coyote. Because as they become louder and more insistent they will drown out your athiest dogma and herald an exciting new dawn for true science.
"Often a cold shudder has run through me, and I have asked myself whether I may have not devoted myself to a fantasy." Charles Darwin
