Yes. I chose to say something only partly right. If I was talking to a creationist, I would suggest that maybe god could have used natural processes to create the world - because if I told them that there was no evidence for a god's action on the universe, they'd assume that I was doing the devil's work and not listen.

If I ended a conversation with my interlocutor's beliefs now being one step closer to the truth, I would feel like I'd done a good job. I can always shift them again next time around.

I take your point about the alternative phrasing. I don't think that that would have undermined my point, so I should have used it.
