When you can find proof that the Bible was written by god outside the Bible saying it was written by god, you might be able to convince me of that. Until then, you're taking the word of a Book that tells you to trust it because it always tells the truth, but the only reason you know it tells the truth is because it tells you it does and you should trust it because it always tells the truth...ad infinitum.
I suggest you read the Gospel of John, paying paticular attention to the words of Jesus. Of course your next reply will be to say,
"How can you prove Jesus actually said these words?"
Jesus says this to those who can hear His voice speaking to them from the words of the Bible,
"My sheep hear My voice, and I know them, and they follow Me; and I give eternal life to them, and they will never perish; and no one will snatch them out of My hand (John 10:27-28).
If you can't or won't listen to the words of Jesus, maybe you have hardened your heart to the God of the Bible, and the truth of John 6:44 is your condition.
"No one can come to Me unless the Father who sent Me draws him; and I will raise him up on the last day."
