Here's an example for you I've seen (and answered) a good handful of times: that the gospels contradict each other about how many angels were at the tomb. (hint: to try to see it that way, one could, but it's missing the forest for the trees)
From Matthew 28 --
1After the Sabbath, at dawn on the first day of the week, Mary Magdalene and the other Mary went to look at the tomb.
2There was a violent earthquake, for an angel of the Lord came down from heaven and, going to the tomb, rolled back the stone and sat on it.
3His appearance was like lightning, and his clothes were white as snow.
4The guards were so afraid of him that they shook and became like dead men.
5The angel said to the women, “Do not be afraid, for I know that you are looking for Jesus, who was crucified.
6He is not here; he has risen, just as he said. Come and see the place where he lay.
7Then go quickly and tell his disciples: ‘He has risen from the dead and is going ahead of you into Galilee. There you will see him.’ Now I have told you.”
8So the women hurried away from the tomb, afraid yet filled with joy, and ran to tell his disciples.
9Suddenly Jesus met them. “Greetings,” he said. They came to him, clasped his feet and worshiped him.
10Then Jesus said to them, “Do not be afraid. Go and tell my brothers to go to Galilee; there they will see me.”
From Luke 24 --
1 On the first day of the week, very early in the morning, the women took the spices they had prepared and went to the tomb.
2 They found the stone rolled away from the tomb,
3but when they entered, they did not find the body of the Lord Jesus.
4While they were wondering about this, suddenly two men in clothes that gleamed like lightning stood beside them.
5In their fright the women bowed down with their faces to the ground, but the men said to them, “Why do you look for the living among the dead?
6He is not here; he has risen! Remember how he told you, while he was still with you in Galilee:
7‘The Son of Man must be delivered over to the hands of sinners, be crucified and on the third day be raised again.’ ”
8Then they remembered his words.
9When they came back from the tomb, they told all these things to the Eleven and to all the others.
10It was Mary Magdalene, Joanna, Mary the mother of James, and the others with them who told this to the apostles.

If one really wants to find a contradiction, the brain can convince itself this has to be one, emphasizing things a certain way, discounting other details.
Nevertheless, in both accounts, there are 2 remarkable individuals they encounter. So, which version is best? Answer: both.
We see the ordinary difference in different witnesses seeing the same event and later telling their own particular versions of the event.
Just like you'd get today if you and your friend witness some multifaceted event, and later each separately write down all details as you remember them, and then compare the precise accounts (or you could both do this with a multifaceted event in the past you both recall) -- you'll find overlap in the accounts, but also unique details in each version. (Do this experiment yourself if you like, with a friend, witnessing something moderately detailed involving multiple people and unexpected actions).
How to miss the forest for the trees -- instead of reading a gospel from the start, reading through, wanting to learn, instead pick out individual bits to 'examine' analytically. This would be similar to thinking one could understand much of a great poem by reading some isolated verses, or a great novel from some isolated paragraphs here and there.
