What was the first ocean to be found?

Probably the Indian Ocean since the most ancient people originated in eastern Africa.

The vast ocean that once surrounded the supercontinent of Pangaea has been named Panthalassa, which would be the first ocean. Is that what you mean?

To determine which ocean was the first to be found, we need to understand the concept of human exploration and geographical knowledge. The term "found" suggests that someone discovered or became aware of the existence of a specific ocean.

Considering human history and exploration, it is difficult to pinpoint an exact first ocean discovery. However, based on available evidence, it is likely that the first ocean to be discovered by ancient civilizations was the Indian Ocean.

The Indian Ocean is geographically close to the region where some of the earliest human civilizations originated, such as those in eastern Africa and the Middle East. These civilizations had the ability to navigate the nearby coastal areas and venture out into the ocean. Therefore, they were likely the first to encounter and become familiar with the Indian Ocean.

It's important to note that the existence of oceans predates human history. The Earth's oceans have been present for millions of years, evolving and changing over time. So, while we refer to the Indian Ocean as the "first" ocean discovered by humans, it is essential to remember that it has always existed as part of the natural world.

However, if you are referring to the first known global ocean, it would be Panthalassa. Panthalassa surrounded the supercontinent Pangaea, which existed roughly 300 million years ago. This ocean no longer exists, as Pangaea eventually split apart, forming the current continents and oceans we recognize today.

In summary, while the Indian Ocean was likely the first ocean to be discovered by humans, it's important to acknowledge that oceans have always existed on Earth. Additionally, if you are referring to the first global ocean, that would be Panthalassa, which surrounded the supercontinent of Pangaea.
