What percentage of Christians believe the Earth was created only a few thousand years ago?

The Earth is FLAT, the star rotate around US, and the Sun TOO! Christians that have a background in science are more likely to believe in intelligent design scenario, in which god said let their be light, and a few billion years later, there were stars! Those not inclined to believe in ID, well, are sticking their heads in the ground! As for the rest of us, we are damned if we do and damned if we dont!
