Which word describes something that has existed from the beginning?

The term "Aboriginal" is used to describe something that is native to a particular region, often referring to the original inhabitants of a land or the earliest forms of something. This word emphasizes a relationship to the original or earliest conditions, highlighting the idea of existence from the beginning. In the context of culture or history, Aboriginal signifies a direct link to traditional practices, beliefs, or existence untouched by outside influence over time.

In contrast, "Ancient" relates to something being very old, but it does not inherently express the idea of being from the beginning or original inhabitants. "Astute" refers to having the ability to accurately assess situations or people, showing shrewdness or intelligence. "Acrid" describes a strong, unpleasant smell or taste and has no relation to existence from the beginning. Therefore, "Aboriginal" is distinctly aligned with the concept of origin and early existence.
