Here's what we know about the origin of Spider-Man:
* Peter Parker's interest in science: Peter is a bright and inquisitive young man who loves science. Attending a science exhibit is a natural fit for his interests.
* The spider bite as a random occurrence: Peter's encounter with the radioactive spider is a chance event. He's at the exhibit for scientific curiosity, not to seek out a spider bite.
* The importance of the setting: The exhibit provides a specific context for the spider bite. It highlights Peter's scientific background and implies a connection between science and his superpowers.
Therefore, the science exhibit is a logical setting for Peter Parker, and the spider bite is a random event that happens to occur there. It's not a deliberate act on Peter's part.
