(21,786 posts)Evolution? We have something called DNA, we know that humans are closely related to chimpanzees, bonobos, and Neanderthals in such a way that indicates a common ancestor (more recent for Neanderthals than chimps/bonobos). We have records of atmospheric CO2 going back nearly sixty years, and global temperature averages, polar ice measurements, etc. The atmospheric CO2 keeps going up, average temperature keeps going up, sea ice density keeps going down, so we know that increased atmospheric CO2 (and other greenhouse gases) are driving observed climate change. Vaccines? We know they work. (look at the differences in infant mortality between say 1900, and now. And when's the last time you heard of a polio epidemic in the USA?). People being ignorant doesn't mean you can't see the proof, because it's there.
