Talking to a Christian
When talking to Christians, they try to use this "proof".
1) Do you agree we exist?
I say "Yes".
2) How did we begin to exist?
3) What started that.
Not being a scientist, I'm perfectly ok with saying "I don't know".
They turn not knowing into "evidence" for a god. I can see this is a total logical fallacy, but they cannot. How can I explain this in a quick manner so that even the most unintelligent christian can understand.
Thanks in advance, all you more skilled atheist debaters.
