Frankly, my dear, I'd have to figure what YOU mean by "young earth creationist." I don't think I am because I have said multitudinous times that each DAY of creation is likely thousands of years old. Understand?
We cannot tell exactly how long each DAY of creation is. That means that although each period of creative time in Genesis is called a 'day,' it obviously from the looks of the earth and -- the growth of life itself, has taken much longer than a 24 hour day. So let me be clear -- the first six days of creation had a beginning and a close. IAll six days are said to have a beginning and close. I'm sure you can see that in the Genesis account. Now I know there are some things you'd to figure out (we all would I think), but -- note carefully -- no matter what a person thinks, the seventh day is not said in the Bible account in Genesis to have ended. OK? Therefore, since this is about SCIENCE more or less, it makes sense that each DAY of creation is far longer than what you might think a "young earth creationist" thinks. Which I don't know what they think, so maybe you can explain what a YOUNG EARTHER believers because I BELIEVE that every day of creation is far, far more than 24 hours human time. Let's try to understand.
