Thank you for the question, “What can we do to educate science deniers?”
I am not sure who you are referring to as “science deniers” and what are those individual denying. To label someone as a “science denier” is to dehumanize that person and suggests even imposes a “re-education” of a person. Be careful, if one uses that approach, then one can “re-educate” any person/people group who disagree with the State. Is the “re-education” of Muslim in China voluntary or compulsory? Freedom of speech and ideas allows for disagreement of views, not an “re-education” to a conformity of a set of ideas.
High schoolers and college graduates are already taught the evolutionary process. Everyone that I know believes that astronauts have landed on the moon, that the earth is not flat, and the question of God’s existence is philosophical and a personal belief. As one already knows, one can’t necessarily “prove” or “disprove” the existence of God since God may not be detected by physical means, at least with the instruments that has been developed.
As a comment, science can educate how a person came into existence, but science can’t educate on the purpose of life for a person. That is a philosophical question in my opinion.
SUMMARY: One can’t eradicate personal thoughts and beliefs.
