What Is The Oldest Civilization On Earth?

It is unscientific to search the oldest civilization using the available contemporary information , because the evidences of the oldest civilization would have either disappeared or deeply buried. There could have been more civilized worlds in the past and could have disappeared in the time run. Most of the western anthropologists disagree with the concept of Dravidian civilization as the oldest simply because they lack scientific evidence.

The earliest known civilizations arose in Mesopotamia between the Tigris and Euphrates rivers in modern-day Iraq, Persia in modern day Iran, the Nile valley of Egypt, the Indus Valley region of modern-day Pakistan and North India, and the parallel development of Chinese civilizations in the Huang He and Yangtze River valleys of China. Smaller civilizations arose in Elam in modern-day Iran, and on the island of Crete in the Aegean Sea, as well as the Olmec civilization and the Caral civilization in modern-day Mexico and Peru.

The Mesopotamian civilization of Sumer is officially is believed to have begun around 4000-3500 BC. It ended at 2334 BC with the rise of Akkad, and is the world's first civilization.

The Egyptian civilization of the Nile Valley started at around 3200 BC. It ended at around 343 BC, at the start of the Achaemenid dynasty's control of Egypt. This is one of the three oldest civilizations in the world.

Indus and mohenjodaro  no argument needed

I will stipulate this is a good answer for this question; however, I hope the reader does not miss the most important point of all:
(a) A bit of the human world is mentioned;
(b) Most of the human world is not mention, including India and there is reason to believe that India is as old as human civilizations became;
(c) But, who knows; we certainly don't but creating an answer to your question took thousands of people numerous centuries being preoccupied with founding & establishing this knowledge.

You are so very wrong, Greeks have over 8000 years of scripted history as well does egypt. For crying out loud moses is 4000 BC and you are now saying egypt is only 3200 bc? Are you mentally ill? Egypt goes way farther back then moses im sure. Greece gave birth to this world.

I agree with the previous statement that there could have been ancient civilizations in pre-history, far outdating current beliefs especially given the long history of the modern human. Some staggering discoveries like the highly debated Tiahuanaco structures and the underwater japanese stepped pyramid, raise questions about the early civilization and technology. I think it would be unscientific to insist a precise date on the oldest civilation on earth. People who were able to move 100 ton monolithic structures 10 miles on mountainous Bolivian terrain and have stone cutting techniques more advanced than modern tech. Are capable  of civilized exhisting. It shows remarkable planning and communication.

The oldest known civilization is that of ancient Sumer. Sumerians developed a thriving agricultural society by the 6th millennium BECE, complete with great stone buildings and even some conveniences that we consider 'modern'. Theirs predates any other civilization by at least a few hundred years. Lemuria is considered fictional.

**If literature is the mark of civilization, then the Aztec civilization must not have existed, as they never kept a written record of anything. They didn't even bother to develop any sort of writing system. My point is that the only 'mark of civilization' is a system of permanent dwellings, accompanied by a fairly complex agricultural <and/or> pastoralism society. **
