I expected this argument. The Ancient Greek word used to describe this relationship between Jesus and David via Joseph is literally "sperma" or "seed". It clearly refers to a very physical, biological connection, and not one by law. So even if these genealogies, once again, were included, they are rendered entirely irrelevant by the later addition of the concept of virgin birth.
So you're an Ancient Greek scholar now? Can you actually read it or did your just read that in a book? Because from what I understand of ANY translation, and particularly languages that are dead is that you have inconsistencies. English does not have a Plural you for instance, whereas Ancient Greek does. Makes for very interesting issues in translating when for instance Paul directs a statement at "you" and the translators fail to specify which you it was in the Greek.
No, it is made up and we can be sure. The things you listed, with the possible exception of Stonehenge, can be very reasonably explained, and we're quite aware of what happened.
We know how they achieved it... we don't know how with their knowledge of Science they actually figured it out.
Well yes and no. We expect it to a certain amount in historical records, but the Gospels would not pass any basic test to establish themselves as reliable historical records at all, based on the contradictions and clear fabrications.
In terms of historical sources, our main sources for the time are Tacitus and Josephus. Tacitus was a Roman historian whereas Josephus was a Jewish one who wrote in Greek. We also have writings of Pliny the Younger and Suetonius. It is on the basis of this extensive understanding of the history of the day that I can make the assertions related to events that operate externally to the internal logic of the New Testament; that is, Herod's slaughter, the census, the Mithraic cults (about whom Plutarch wrote in his "Life of Pompey" which predates Christianity by some 60 years).
I do actually know Josephus' Jewish antiquities, I know about Tacitus' Histories and Annals, I also know about Pliny the Younger's writings to Emperor Trajan, I know about Suetonis' Lives of the Caesars.
We could also talk about Thallos, Mara bar Serapion, Lucian of Samosata, Celsus... references in the Talmud to events in the New Testament.
I do actually know a little about this subject...
