Hi William:
I did honestly research this topic a few years back. I was studying various religions and trying to make a decision on what to do and decided to start with a clean slate - not taking for granted that Jesus or God even existed. I found that there is evidence of Jesus' existence outside of the bible and Christian writers - Josephus is only one example, there are other letters and historical documents from political leaders of the time that speak of Jesus and the christian movement. Perhaps you should do a little more research on this.
The thing that made me really believe in Jesus was studying prophecies that he fulfilled - mainly in Isaiah and Daniel. Since the Old Testament scriptures were translated into Greek (the septuagint ) prior to Jesus' birth we know they were in existence before he arrived on the scene. To add to this is the fact that a large portion of the Isaiah text was found with the dead sea scrolls - dating well before his birth. Isaiah contains numerous prophecies about Jesus including events surrounding his birth as well as how he would die.
Daniel outlines the time when Jesus would be born.
Daniel 9:25 Know and understand this: From the issuing of the decree to restore and rebuild Jerusalem until the Anointed One, the ruler, comes, there will be seven `sevens,' and sixty-two `sevens.'
...The First Coming occurred exactly 483 years after "the issuing of the decree to restore and rebuild Jerusalem,". The Jews of that time knew the time table - hence the reason why so many asked both Jesus and John the Baptist "are you him"? They were expecting a messiah.
Combining that with the fact that this "Jesus" has made the largest impact on human history of any individual - even our calendars are based on his birth.
There have been individuals that have made huge impacts on history - but none have reached even close to the impact of Jesus - nor have they fulfilled prophecies on this level that could be proven were written prior to their existence.
