What is best response to " Science was wrong before, therfore it's not trustable" ?

I'm not sure this question is related to this plece, but i want to hear everyone opinions. Im tired of some religious people ( creationists ) who always say that scientists don't know all the answers, they were wrong before, therfore they are wrong and we are right. But they belive that whole universe is created by god, scientists are understanding the creation of god, what are they worrying about? Everything must be sign of god ( including evolution ). when they say science doesn't know all the answers they are admiting that universe is so complex, if it's so complex then why they are sure that creation is right and evolution is wrong.
