See here is one of those classic unchristian young-earth/global flood insinuations that they are the ones who accept the miracles. Local flood proponents believe in the miracle of the flood as well. If global flood people actually read what they local flood people say, instead of what other people tell them they say, the global flood people would know this is what the local flood proponents believe: A massive flood in the Middle East occured early in man's history when they hadn't yet left the area and destroyed civilization.
But some people just don't want to actually learn what they are talking about before they pretend they already know.
People who assume they already know they are correct on what the Bible reads aren't actually taking it seriously.
The first miracle in the bible is that God created the heavens and the earth in six days. Do you believe that Miracle? How about the parting of the red sea? Do you accept that? Was that a "natural" event or can God suspend the laws of nature in order to do his miracles?
Do you believe in the Miracle of changing water into wine? Walking on Water? Feeding 5000 with a couple of fish? Healing a man born blind? If you believe all that, then why can't you believe that God did what he said in Exodus Chapter 20?
