Seriously, this stuff is kindergarten stuff.A few key points:
They cannot even agree on who the father of Joseph was.
Long after Matthew and Luke wrote the genealogies the church invented (or more likely borrowed from the mystery religions) the doctrine of the virgin birth.
Of all the writers of the New Testament, only Matthew and Luke mention the virgin birth.
1. The gospel writers contradict each other.
2. The gospel writers rewrote history when it suited their purposes.
3. The gospels were extensively edited to accommodate the evolving dogma of the church.
4. The gospel writers misused the Old Testament to provide prophecies for Jesus to fulfill.
A simple examination of the counter arguments would resolve these.
Its not worth bringing up here, go read some websites that deal with it, is my suggestion.
