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.
This should answer all of your questions.
Matthew 25:31-46
31 When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:
32 And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:
33 And he shall set the sheep on his right hand, but the goats on the left.
34 Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:
35 For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in:
36 Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me.
37 Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink?
38 When saw we thee a stranger, and took thee in? or naked, and clothed thee?
39 Or when saw we thee sick, or in prison, and came unto thee?
40 And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.
41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
42 For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink:
43 I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not.
44 Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?
45 Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me.
46 And these shall go away into everlasting punishment: but the righteous into life eternal.
This doesn't answer anything.
God wants us to enjoy our lives in this universe and to grow as souls. We obviously need many many lives to achieve the state that Jesus achieved: ego-death. And this is what will get us into the Kingdom of God.
This is how a good God will arrange creation.
Ego-death, eh? Who's assuming they know more than the Creator of the entire Universe exactly?
Isaiah 55:6-13
6 Seek ye the Lord while he may be found, call ye upon him while he is near:
7 Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the Lord, and he will have mercy upon him; and to our God, for he will abundantly pardon.
8 For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord.
9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
10 For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater:
11 So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
12 For ye shall go out with joy, and be led forth with peace: the mountains and the hills shall break forth before you into singing, and all the trees of the field shall clap their hands.
13 Instead of the thorn shall come up the fir tree, and instead of the brier shall come up the myrtle tree: and it shall be to the Lord for a name, for an everlasting sign that shall not be cut off.
Who's assuming that the people who wrote the bible were right in everything and all of them had our best interest in mind?
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.
