The Case About a Traveler In English Text

The Case About a Traveler In English Text occurred when I was in the 10^th form in high school.
We read a text in our Students' books about a traveler who went with his girlfriend on a trip. I can't really say where did they go, but it was a harsh traveling and the girlfriend left the traveler. But he did not stopped and continued his adventures. He had been to some amazing places (I do not remember exactly) and then one day he saw a rainbow and it was beautiful and the traveler thought that there was a God above him.
And the teacher asked me why the traveler became so religious. And I answered that a lot of time had passed since he began traveling and he never met a scientist but only people without higher education or with no education at all. And my teacher did not understand me. And I had to tell her something like "He saw a wonderful sight and was impressed by it", which was a satisfactory answer.
But what I meant was that if a person deals with people who have no education or poor education he should be cautious not to degrade. But this traveler was not cautious enough.
I am an atheist. Sorry I may have insulted somebody's views here.
