Your response doesn’t answer all of the questions.
How do you know they’re from the apostles?
How do you know they’ve been written into the Gospels faithfully?
What is the source for verifying all of the above?
Can you provide authentic, reliable, information documenting who wrote the gospels, when they were written, and where they were written.
You have evidently not studied the many and varied attempts to discredit them. I would suggest you do so. It's very enlightening.
