Why don't we know the date Jesus rose up from the dead?

[Thor]

the account of josephus is not an elligible account for christians. even though it is much exact in terms of historical events, there are some differences in the four synotic accounts. why don't you debate with christians using the accounts christian's used?
its just shooting a bird but you have shooted a fish..

There have been numerous times where I have debated a Christian and pointed out that there is no evidence that "Jesus" was a real person, and they cite Josephus as evidence that he did exist. So, I am debating Christians with "the accounts Christians use".

BTW, the past tense of "shoot" is not "shooted".
