"So in order for us to accept that your creation hypothesis is true, we have to first assume that it is?"
No quite, Ellie. This thread is not about my creation hypothesis or evidence for God's existence. It is about young earth creationism.
I could have this same discussion with a theistic evolutionist who believes God used evolution over millions of years. She would already accept my 3 preliminary assumptions and the questions would switch from, "How do you know God exists?" and "How do you know the Bible is true?" to "Why do you think the Bible teaches God created the world in 6 literal days?" and "Why do you think evolution is false?"
"I know that's not what you think you're saying, but when you strip it down in fact you are."
No, it really isn't, Ellie.
"We could all do that, couldn't we?
Me: Scientists - I have a theory about the beginnings of the universe.
Scientists: OK?
Me: Please first assume that my belief is correct that it was started by a giant cosmic purple farting hippo called Nigel
Scientists: OK. We'll accept that - because that's what we do. We accept things for absolutely no good reason.
Me: My model predicts that if I'm correct, hippos should be evident in nature as a mortal incarnation of Nigel, we should feel his farts as wind and the colour purple should be pleasing to the eye.
Scientists: Makes sense.
Me: Well, hippos exist. Wind exists. Purple is a pretty colour.
Scientists: My God...that's amazing. And we thought Einstein was clever! Can I have your autograph?"
A cute story and it made me smile but it's irrelevant to this discussion.
"I don't accept your God exists because I have no reason to"
And I don't accept your lack of a god because I have plenty of reasons not to. But those reasons are irrelevant to this discussion. I have posted links to my evidence for God numerous times throughout this board.
"and science doesn't work like that.
You begin with an observation. Develop a hypothesis to explain that observation. Test, test, test. Present your findings to your peers. They test, test, test. If they can't prove you wrong, then you may be on to something."
An excellent description of the scientific method and one which all young earth creationists agree with - namely because WE invented it.
