Offering my own opinion on the virgin birth is not arbitrating. There is no dispute to settle, unless you are disputing that there was a virgin birth? Even if you do dispute the virgin birth, your opinion (or anyone's opinion) is as valid as mine.
In my opinion, any creation of God's is a miracle in my eyes. Are you, by chance, referencing a literal 24 hour/day six day creation? The Hebrew language, just like English in this case, defines 'day' in different ways. (English has 15 definitions for the word day.)
When English references "The day of the dinosaur" Webster is not insisting that all the dinosaurs lived one single day. The same can be said about light. "In the day of light creation" can mean a period of time when light was coming into being. The Old Testament has other examples where the Hebrew word that defines a 24-hour period, also defines a long period of time that began and ended. such as the day of King David.
Science and language offer different alternatives to events poofing into existence in a 24-hour time frame. It is quite unnecessary for any creation by God to take place within a limited time. For example, the angel did not announce that Jesus would be born to Mary on one day, then have that birth take the day after, on the second day. Mary was pregnant for the usual nine months.
Another example: Raising Lazarus from the dead. What is the alternative to that miracle story? There is none. We either believe John is relating a true event, or that he made the whole thing up. My opinion is that John is writing a true biography. The details of the account match the customs of that time.
