Do you really think ALMIGHTY GOD would have a problem having only GOD inspired men to choose only GOD INSPIRED (GOD BREATHED) books to be included in His Holyword???? THINK!!!
"Holyword"? Interesting -- at first glance it looked like "Hollywood". And eerily appropriate.
Here's your problem, and it's as old as theism itself:
The problem is, you don't realize that all knowledge is based on ultimate authority, which is circular reasoning.
How do you know
Ohm's Law is true?
Well... I was taught it in school. Who taught it? My teacher. Where did my teacher get it? He read it in a book. Who wrote the book? Georg Simon Ohm. Where did he get it? Well he tested it, and it worked. How do you know? Because Georg Simon Ohm said so, and no one has been able to prove it wrong.
In all knowledge there is an ultimate authority. When you trace knowledge back to the ultimate authority, you automatically end up with a circular logic scenario.
How do you know Newton's laws of motion, are true? Because Newton tested it, and it was right. How do you know? Because he said so, and no one has proven it wrong yet.
Similarly, I believe in Jesus Christ being G-d, that came to Earth as a human, preached for 3 years, was killed for our sins, came back from the dead, and is now in Heaven awaiting His return.
Where did I get that? From a book. Who wrote the book? A number of people. Where did they get that from? They lived it, and were with him at the time. How do I know? Because they wrote it down, and no one has been able to prove it false yet.
Circular? Yup. But no more circular than people who believe The Code of Hammurabi exists. There is an ultimate authority at some point, for all knowledge.
