There's evidence that Jesus travelled to India and Tibet in his younger years, there where the bible says he was a carpenter during those years. There's many video's on this subject. Here are just two:

This is important to know because it helps us to understand what Jesus really meant with that you have to go through him to enter the Kingdom of God. What this really means is that you have to become ego-less (like Jesus) to enter the Kingdom of God.
In Eastern traditions this is often referred to as ego-death or Enlightenment. And to achieve ego-death we need to go within. "Know Thyself" and "The Kingdom of God is Within" is what Jesus said.
Praying really hard to God and Jesus and accepting Jesus as your saviour will not get you out of the reincarnation process. And yes, there is evidence that Jesus originally spoke about reincarnation as well. But obviously the TPTB did not want to empower the people and therefore they would have had enough motivation to scrap reincarnation from the bible.
If you don't achieve ego-death, like Jesus, in this lifetime you don't have to worry. As long as you did not live your life in a completely selfish manner, you will go back to that place called heaven and then after a while you decide to reincarnate again. Even if you do end up in hell (which will feel like an eternity) you will get a chance again to redeem yourself. Even our brothers and sisters from the darkside were created by God.
Don't let dogmatic believers convince you that you only have one chance. People saying you only have one chance should have a good hard look at themselves. Instilling people with fear is not a good thing and is not what God and Jesus are about.
Isaiah 46:9-11
9 Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me,
10 Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:
11 Calling a ravenous bird from the east, the man that executeth my counsel from a far country: yea, I have spoken it, I will also bring it to pass; I have purposed it, I will also do it.
This chapter in Isaiah issues the biggest challenge ever to somebody with your mindset.
The prophecies in the Bible are the proof.
Find a failed prophecy and you know it's all a bunch of BS.
In all my time studying the Bible, I've only found further confirmation of the truths it contains.
One thing I will point out is there are very flawed characters in the Bible. Before he was renamed Abraham, Abram lied to stay out of trouble and got himself in more of it time and time again but didn't learn right away. Moses was a stuttering murderer. Noah got blackout drunk. David was an adulterer and a murderer, etc. Much more believable than fantastical gods who can do no wrong.
