Maybe some of us are more concerned with truth than our image. Consider that the propaganda campaign for billions of years has already spent hundreds of billions of dollars to create an orthodoxy of dubious science. There are many problems with old earth "evidences" and even more for godless existence; I for one will interpret the rocks by the Bible and not interpret the Bible by the rocks. I find special revelation to be the superior epistemological standard to general revelation. It is socially more costly to stand for truth and oppose the well-funded majority opinion, but truth is independent of your belief or even your ridicule.
I’m not ridiculing anyone, just stating a fact: Creationists tend to make Christians in general look like nutjobs to the average observer. That’s the sad reality. try arguing with someone on the Left about this and you’ll instantly see what I mean.
You are free to believe anything you like, but Creationism isn’t good science. And we don’t need Creationism to be saved.
