You do realize the gospels are eyewitness accounts and have been harmonized countless times, right?
Suppose this happens and there are three eyewitnesses:
A man, his wife and their small child are in their car and driving down the road. The man is driving, the wife is in the passenger seat and the small child is in the back.
While driving down the street, a cat suddenly darts from behind a tree and into the road in front of the car. The man freaks out and slams on the brakes. The wife screames and reaches over and yanks to wheel to try to avoid the cat, and the child ducks down in the back seat, but the car swerves and runs into a tree.
Now a police officer comes out to investigate the accident and talks with the first witness who was positioned in front of the car and he tells what he saw, a cat darting in front of the car, screeching brakes, screaming woman, hitting tree.
The second witness was on the sidewalk beside the car when the accident happened and he tells his story, screeching wheels, screaming woman grabbing the steering wheel, kid in back ducking down, hitting tree.
The third witness saw the accident from behind and tells his story, screeching wheels, screaming woman, kid in back, hitting tree.
All three stories are different and all have different details, adding some and omitting others. Now, which one lied?
None of them. They were all 100% accurate in what they saw. Only one saw the woman grabbing the wheel, but it doesn't contradict any of the other stories any more than only one witness seeing the cat that caused the accident but not seeing the child in the backseat the other two witnesses saw.
The gospels are eyewitness accounts and they do harmonize. Just put some effort into figuring out what you are reading before talking about "inconsistencies".
