How long have humans been on Earth?

What is the real calendar of human life? What is the calendar of earth’s existence? How do we work out a 100% accurate calendar, similar to the atomic clock, which accurately keeps time? Nobody knows what year we are in, in reality. The whole world has been brainwashed into thinking that the year is according to a calendar based on some religious people thousands of years ago. If you ignore the stories and dates of the religious books, you will see that a problem remains. What year is it actually??? A calendar is only a timeline of religion, which is a small period of human existence. Religion is morals and values and history mixed with fantasy. Why should people in this world just accept an invented calendar that only represents religion? The current year is not 2008. The current year is unknown. There are currently about 40 calendars that are used by different countries, and none of them agree with each other. The most popular internationally used calendar is the Gregorian calendar,

Between 100,000 to 200,000 years. (See Source 1.) The main question is not the dating of fossils, but defining what is “human” … i.e., at what point would H. erectus be more correctly called H. sapiens, as these are just arbitrary distinctions defined by anthropologists. The evidence includes the rapid expansion of cranial capacity in fossils dated in the Mid to Late Pleistocene epoch (about 250,000 years ago), and the arrival of stone tools. I don’t know where people get the idea that the dating of these fossils is done with carbon dating … C14 has a very short half-life making carbon dating accurate only to about 60,000 years (which is a lot longer than 6,000 years, but not nearly long enough to date most fossils), and can only be used on once-living carbon-based material, which does not include stone tools and fossils. Instead, this dating of fossils and stone tools is done with other forms of radiometric dating (e.g.

The earliest human writing was found 5500 years ago. (which is what I would use as evidence of reasoning). Chimpanzees can use tools But I suppose it depends on how you define us as humans. ______________________________________… Just for the record I’m not a creationist, I believe in evolution. Just trying to take a different slant on answering the question. Writing denotes a highly evolved method of communication, defining a culture or society. Probably Human Culture existed before this time but writing, IMHO shows an evolved level of critical thinking akin to human society as we know it today. Again Not a Creationist!!!!

Well the Tlingit Alaska Native Americans go back 14,000 years and Native American archeological evidence goes back 14,000 years or so. So while I can’t say how long humans and including Cro-Magnon go back I can say it was a hell of a lot longer than the 6,000 years some claim! So I would agree more with the 40,000 to 90,000 year answer above.

Human remains have been found in Africa that date back to about 200,000 years ago, so humans have been on Earth for much longer than 2007 years. 2007 is the year in relation to the birth of Jesus of Nazareth. In fact the year is 2007AD (Anno Domino), which means “In the Year of Our Lord”. And the BC in dates is “Before Christ”. Technology has always been around. Technology is not just computers and planes. It’s perceived as anything that is made by man to serve their purpose. Early humans had developed technology to serve the needs that they had, like: utensils, weapons, fire, the wheel, etc… And as human needs and wants evolved so did our technological endeavors to serve those needs and wants. Plus, as humans evolved into the species that we are today, our brains evolved as well, thus giving us the capability to wonder and discover more. Technology wasn’t sudden, it was evolved. As for the question about English; if in fact you mean the specific language of English, well humans lear
