There is a difference between and egg, and an embryo that is the result of an egg fertilized by an sperm. Apparently many people on this thread are confused. An egg will never become a baby, unless it is fertilized and an egg is no longer an egg after fertilization, and can never become one again.
While others might be confused (though I would never make that assertion) I know I am not. I just happen to disagree that an artificially fertilized egg lying in a petri dish is a human being.
You, of course, are entitled to your opinbion and I'll respect it. I'm entitled to mine.
