One would think that if there was a God and it knocked up a virgin so it could be born in the flesh here on earth, that someone would have noticed but no one did. So Christians being Christian altered ancient texts by inserting mention of Jesus into them.
And still Christians want us to accept them as credible. They just don't get it.
"Christianity: Because you're so awful, you made God kill himself."<quoted text>
God screwed a little girl to give birth to himself so he could kill himself to make himself happy.
And then they wonder why we don't believe it.
