I'm YEC myself.
I can't remember where I first heard someone bring up the miracle of Jesus turning water into wine in the midst of this discussion, but it's always been helpful to me.
When God creates something miraculously, understanding that miracle with the structure of the natural process supporting it will make us draw logical conclusions that don't necessarily have to be true for the miracle.
For example, Jesus can turn water into wine with just his word. He declares it to be and it is. He speaks it into existence. However, it would be easy to look at the wine from a "natural" perspective and say, "this wine must be *x* number of days old because we know the fermenting process takes this long. And *x* type of grapes must have been used based on the alcohol content of the wine....... etc."
A miracle done by God can allude to appearance of age when you overlay the understanding of the "natural" process over it; however, God simply spoke it into existence.
Not sure if that helpful for anyone else, but it's been helpful for me.
