"Except when it is in favor of evolution."
No. Not then either. A poll of people not involved in the sciences has no relevance to science. Period. It doesn't matter how the poll turns out. Science does not use polls to determine facts.
No that is not true as far as evolutionists are concerned. There was quite a fuss about 400 scientists named Dave signing a letter in support of evolution as well as a number of other polls of educators and "scientists" that come up from time to time.
Evolution is only possible if there is no creator as Darwin explains in his thesis.
