You will never change their minds, and the more you poke their entrenched beliefs, the more angry they become.
What might be more useful is to find out from them why they are so determined that everyone else has to share their belief, to the extent that they establish so-called "museums" to promulgate it; and at one time at least, even made it illegal to teach anyone anything about evolution, in some American states.
A policy they tried to bring into British schools, exploiting a governmental decision I think wrong anyway, to hand schools over to so called "Academy Trusts" - commercial organisations. Fortunately the "Commercial Creationists" as I call them, failed because British school syllabi and curricula are not controlled by self-serving local politicians and parents. Instead the education and welfare have to at least meet national contents and quality standards; and the education leads to nationally coherent school-leaving examinations. Your results in those influence your ensuing employment or higher education: the point of school is to prepare you for your own life as an adult.
Most scriptural literalists are so individually, safe from learning or thinking - including whether they are unwittingly denigrating their own god. That is entirely their own choice. They do not have to follow it. They are free to keep to it or to change their minds; free to change to a different sect, or faith, or to abandon religion altogether. They should Thank their God for these basic freedoms that theocracies refuse!
However, I accuse the literalist organisations of dark motives beyond silly anti-science preaching (over the Internet???), and it is very hard to pin them down on that. Ask one, and he or she will dodge the question; either by genuinely not knowing personally, or perhaps wanting to hide something.
