there are many non-christian historical sources, who had no reason whatsoever to support the existence of the man Christ Jesus, that wrote of His life, controversy and death. the roman pliny and the jewish historian josephus for two.
that's on top of around 6,000 surviving new testaments, 99% of which concur. He lived, He was the second adam, and the only way of redemption for all mankind.
you have a court case after you're dead - not immediately, but when the time comes, every one will have one, and you will stand before the King and He will read out your crimes against others and Himself and the Creator, all the things you've done in secret that have harmed others in some way, how you gonna plead?
the buddhist karmic endless incarnation idea never really made sense even when i was more new age like today's spiritual zeitgeist - there is no moral imperative there, what is the impetus to do good?
now this is not a rewards for good behaviour deal at all - this is where many are mistaken, including many churches and many other religions. the point is that Jesus paid the price for all of your sins, because He loves you, and so does God. all you have to do is accept this, and change your life accordingly.
contrary to what you might have heard, God is merciful, loving, kind, generous, giving, wanting all to come to repentance and to know Him and especially to take part in the next eon and the delights He has planned for those that love and trust Him.
what's not to like?
