If I may add my two cents here, I have found the socratic method to be highly effective in these situations. When they make a claim like, "Evolution is a religion." Ask them why they think that. If they say because its a myth - ask them why they think its a myth. If they say its just a theory - ask them what they think a theory is. Ask them if they accept the scientific theory of gravity, atomic theory, or germ theory? If they say yes they accept those - ask them why they accept those but not evolution. What metric are they using to discrimate between them?
The point is, keep asking questions. Keep the burden of proof on them. They're the ones making the claim that evolution is false. When they start getting fusterated because they can't support their position, then you start in with your facts. It will then becomes apparent to them, even if only on a sub-concious level, that there is a huge difference between their position of just making assertions vs. your position of actually having evidence that supports your claims.
Why do I believe in evolution? Because it is supported by all the life sciences such a developmental and molecular biology, embryology, ontogeny, osteology, paleontology, etc. Because the genetic evidence is overwhelming. Mitochondrial DNA, alone, proves common descent. Endogenous retrovirus’, alone, prove common descent. The Y chromosome, alone, proves common descent. The genetic evidence is undeniable. And it falls perfectly in line with other things like atavisms, physiological and molecular vestiges, biological and chronostratigraphy, geographic speciation, the nested hierarchy of phylogenetics, ring species, transitional fossil forms, and a million and one other things. And because evolution is an applied science, without understanding evolution we couldn’t produce antivirals and antibiotics. That’s why I believe in evolution. Now tell me again self righteous elder, why do you think its false?
Sorry, didn't mean to rant there. Gets me worked up too!
