Answer:
Locke's point is about the nature of memory and how we come to know things. He argues that memory alone is not enough to establish the truth of a claim because memory can be fallible and subject to error. Just because we remember something vividly does not necessarily mean it actually happened. Instead, Locke suggests that knowledge comes from the combination of sensory experience and reasoning, and that we should be careful to base our beliefs on reliable evidence rather than just on what we happen to remember. By using the example of Noah's Ark, which is a legendary event that supposedly happened thousands of years ago, Locke is highlighting the fact that memory alone cannot be relied upon as a basis for knowledge.
