Debating with a creationist

[OnlyNatural]

Fossils of common ancestors and transitional species would be a start. Do you know of any?

I'm actually taking a course in biological anthropology right now, and there are many fossils of common ancestors, as well as transitional fossils. Is he looking for transitional and common ancestor fossils for all sorts of different species, though, or just for humans?

And where did the single-celled common ancestor come from? Atheists need to provide a naturalistic explanation for that too because if God just put it there then that destroys their entire worldview which revolves around the conviction that there is no God.'

Looking into abiogenesis would be a start. It explores the first origins of life, and whether life can come from inorganic matter. Here's an article and the Wiki.
