Actually, it's a perfect example that people who claim to know the divine can't interpret correctly a simple chapter. Read the whole chapter.
You state that you don't even know if God exists. That renders you singularly unqualified to correctly discern and interpret any writings about or by Him.
If you want any credibility in your statements about theology, Scripture, any spiritual matter, you need to know it.
You're no different than a blind man telling a sighted man that he's wrong about what he sees.
Or are you now telling us you're an expert in magic books or something you don't know?
You’re ignoring Matthew 1:18 Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit. 19And her husband Joseph, being a just man and unwilling to put her to shame, resolved to divorce her quietly.
20But as he considered these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. 21She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” 22 All this took place to fulfill what the Lord had spoken by the prophet:
23 “Behold, the virgin shall conceive and bear a son,
and they shall call his name Immanuel” (which means, God with us).
24When Joseph woke from sleep, he did as the angel of the Lord commanded him: he took his wife, 25but knew her not until she had given birth to a son. And he called his name Jesus.

I’ve posted this to you before and you have not responded to it. You’ve ignored it. So I’ll ask you the question again. Matthew says that it was fulfilled prophecy.
Was Matthew lying when he wrote that?
Why should we believe you over him?
