I remember about 1979-80, I was reading a book, I believe "Broca's Brain" by Carl Sagan and he mentioned how JWs kept sending him copies of "Did Man Get Here by Creation or by Evolution." He then picked it apart. Their arguments haven't really changed. All creationists do nothing more than look for supposed flaws in evolution and then use the "god of the gaps" fallacy so since it's not evident beyond a shadow of a doubt then god did it. They never, never offer any type of evidence themselves but simply attack a scientific theory that is probably the most verified and proven scientific theory today. All creationists use this approach that I have seen. As for me, it was only a couple of years later that I completely weaned myself from that horrible religion.

You can find a shitload of this kind of thing simply by doing a search using the right words on youtube.

Tell her the Universe has always been here - there was no beginning - matter has been exploding and contracting forever. And sometimes when the conditions are right, molecules can collect in a way that they become the building blocks for life. Over billions of years an explosion of life occurred on this planet. And that's how we got here.

Yeah. Spend your time for yourself, not others. Did you give him a book to read?
