Hey guys, I need some debating advice. I'm being emailed by a Creationists from another website. I basically tried my best to explain to him why evolution is the best explanation for the origin of the species on Earth, explained to him that it is a gradual process.
He is now claiming that the only reason scientists claim that is gradual just so they can back it up. I don't accept that.
How do I put in simple words exposing the evidence that it is indeed a gradual process.
