modern human being existed

Is it people left written records, people created calendars, or people began to study history

Yes, all three of these statements are true.

1. People left written records: Writing systems were developed by various ancient civilizations, such as the Mesopotamians, Egyptians, and Chinese. These written records captured important events, stories, laws, and other forms of knowledge.

2. People created calendars: Ancient civilizations also developed calendars to track time and seasons. Examples include the Mesopotamian calendar, the Egyptian calendar, the Mayan calendar, and the Chinese calendar.

3. People began to study history: As societies developed writing systems and left written records, the study of history became possible. Ancient historians like Herodotus, Thucydides, and Sima Qian documented past events and tried to analyze and interpret history.

These three elements showcase how modern human beings have progressed in terms of recording and studying their own history.

modern human being existed only one answer can be selected not all

Apologies for any confusion. If I have to select one answer, then the answer would be "people left written records." Writing systems developed by ancient civilizations allowed for the documentation of important events, laws, stories, and knowledge, which is crucial for studying and understanding history.

right and responsibility does equal treatment go in right or responsibility

Equal treatment generally falls under the category of "right" rather than "responsibility." Rights typically refer to the entitlements or freedoms that individuals possess, such as the right to life, liberty, equality, or non-discrimination. In this case, equal treatment can be seen as a right that individuals should be entitled to, irrespective of their characteristics or background. It implies that all individuals should be treated fairly and without any bias or discrimination.

what about fair and speedy

Fair and speedy often fall under the category of "responsibilities" rather than "rights." In the legal context, for example, fair and speedy trial is considered a responsibility of the judicial system. The responsibility is to ensure that individuals are given a fair and impartial trial in a reasonable timeframe. This means that both the fairness of the trial proceedings and the expeditious resolution of cases are seen as obligations of the legal system. However, it's worth noting that different societies and legal systems may have variations in the interpretation and implementation of these responsibilities.

what about stay informed

"Staying informed" is generally considered a personal responsibility rather than a right. It is the individual's responsibility to actively seek out information, stay updated on current events, and be knowledgeable about various subjects of interest. Being informed allows individuals to make educated decisions, engage in meaningful discussions, and participate in their communities. While access to accurate and reliable information is crucial, the act of staying informed is typically seen as a personal duty rather than a guaranteed right.

The modern human being, Homo sapiens, has been around for roughly 200,000 years. However, the development of writing systems, calendars, and the study of history occurred at different points in human history.

1. People left written records: Writing is a crucial tool for recording information and communicating ideas. The earliest form of writing, known as cave paintings, emerged around 40,000 years ago. These early drawings served as visual communication but were not written records as we understand them today.

The first known true writing system was developed by the Sumerians in Mesopotamia (modern-day Iraq) around 3200 BCE. This writing, known as cuneiform, used wedge-shaped marks on clay tablets. From there, various writing systems evolved independently in different parts of the world, such as hieroglyphics in ancient Egypt and ideograms in China. These written records preserved important information and historical events.

2. People created calendars: Calendars are tools used to track and organize time. They are essential for planning agriculture, religious ceremonies, and societal activities. The earliest known calendars were devised around 12,000 years ago by ancient civilizations like the Mesopotamians, Egyptians, and prehistoric peoples of Scotland and England.

The ancient Egyptians developed one of the most well-known calendars, which was based on the cycles of the Nile River and the movements of the stars. Other civilizations, such as the Mayans, Greeks, and Romans, also created calendars tailored to their specific needs. These early calendars not only helped with practical purposes but also played an important role in recording historical events.

3. People began to study history: The formal study of history as an academic discipline emerged much later than the invention of writing and calendars. The ancient Greeks are often credited with laying the foundation for historical study. Around the 5th century BCE, Greek scholars, known as historians, started questioning and analyzing the past to understand the causes and consequences of events.

The ancient Greek historian Herodotus is often considered the "Father of History." His work, "The Histories," marked the start of systematic historical inquiry, focusing on the Persian Wars and the cultures of different peoples. Over time, historical study evolved and spread to other civilizations, such as the Romans, Chinese, and medieval Arab scholars.

So, to summarize, while modern humans have been around for thousands of years, the development of written records, calendars, and the study of history took place at different points in human history.
