The climate of the Sahara was completely different thousands of years ago. And we’re not talking about just a few years of extra rain. We’re talking about a climate that was so wet for so long that animals and humans alike made themselves at home in the middle of the Sahara.

@@chriszelez7970 Yes we can. The reason the Sahara warmed up and cooled down is because of Milanovich cycles which cause glacial periods and warm periods. Problem is, today we are suppose to be cooling off, not warming up. By now we should be headed back into a glacial period but we are not. That is due to man made CO2 based global warming.

I worked in the Libyan desert in 1980. There, about 280km south of the gulf of Sirte near Zilah we saw a larger area of hundreds of petrified trees. Many sections were a few feet in diameter and several feet long and tree rings were perfectly preserved. The petrified wood was a shiny black rock, very heavy.

The rock artist were really artists. The detail and dedication it took to carve those drawings into solid rock is astounding and awe-inspiring. One question though; one picture is of a human and a giraffe but it looks as though the giraffe is eating from the human's hand. Would it be possible to train a giraffe to do that? I mean not in a zoo or place where the giraffe had access to its normal diet and didn't need to depend on humans for food. In any case the scene is so peaceful and gentle it almost makes tears.

Humans can tame any animal the question isn't IF we can do it but WHY would we do it? However as many cultures have tame elephants for heavy lifting I could see giraffes being used as scout animals with a harness on it's back allowing someone to climb up and see clearly across long distances. Or simply as a meat animal, that long neck is all muscle, the rest of it is just a bigger version of horsemeat and because it grazes on trees it won't compete for the lower grasses that goats and oxen would eat.

The Sphinx is built near the Nile River which floods regularly. So the Sphinx doesn't need to be considered older than it's current estimate (4500 years old at 2500 BC) to have water erosion marks. And even 4500 years ago means it could have lingering elements of the African green period where there was more rain and more waters in the rivers (eg. More floods).

It's crazy to think about how The Old Kingdom of Ancient Egypt began only a few hundred years after the end of the African humid period. The area around the Nile probably was still a lot more green. I'd love to see what it looked like. Also, it was because of this that there were still lions in North Africa for the Romans to capture during their time.

@Nghilifa Год назад

Small groups of the North African lion(s) survived into the early 1960s (they're called "Barbary Lions") I believe, so people alive in North Africa today have seen/witnessed lions in their lifetime(s).

Interesting video to say the least. I am west african and in our ancient lores many ethnic groups in this region always seem to point to their origins being further north on the continent, I guess it would make sense that populations would remain on the northern coast or drift further south along with the rains. This further goes to show the significance of climate change on human history; A Sahara that stayed green would have meant stronger links for trade, dissemination of ideas and civilization building. The Sahara is also half a continent of land not arable and going to waste, imagine the scale of arable land available in a green Sahara with large lakes! At the current level of global warming another green Sahara might be in the works

If the Saraha dried up around 5000 years ago would that mean that it could have indirectly lead to the evolution of ancient civilizations such as the Sumarians and the Egyptians? The idea of the Saraha being green is a tantalizing one and the thought of how much viable land there would have been suggests that people may have spread out a lot in those times. Losing all of that and huddling around water sources like a fire in the night may have been what sparked civilization on a large scale. Thanks for the great video, so much fun food for thought.

Human society as we know it today (with people living in cities and agricultural technology and domesticating animals and the use of science and technology) would perhaps not even exist without this climatic change. Sp maybe the current climate change can be a driving force for new innovations and technology to deal with a more rapid change in climate, like finding ways to produce food with less water, regreen deserts, and to change from fossile fuels to renewables and nuclear.

@Mari-gn8su 3 месяца назад

I think your right lol. The Sahara desert formed in approximately 300 years, a time span equivalent to the duration between the present day and the signing of the Declaration of Independence. I assume that people likely flocked in areas abundant with resources and engaged in rapid trade. This likely also triggered the agricultural revolution, as the scarcity of fresh fruits and vegetables in the desert would have made them increasingly difficult to get. This may have also provoked the beginning of conflicts among mankind to assert dominance over land.

A green Sahara would change the entire history of the Mediterranean. It’s hard to say whether a great land power would form in the hospitable land, or if it would’ve turned into a open plain for nomadic peoples like the Eurasian steppe. It’s also hard to say how impactful Egypt and Mesopotamia would’ve been with large plains to settle instead of being constricted to river valleys/flood plains.

@szzk7937 4 года назад

They are the Ancient Egyptians they just went to Nile. If it were still green today, cultures would just spring up on the Southern Mediterranean first as opposed to the north eastern shores. I don't think it would change, Rome like place would start in Egypt as opposed to Italy first.

@grumpyaustralian6631 4 года назад

I'm sure its possible given enough time and luck, but generally speaking Olmecs and Aztecs aside, civalisations appear to be more probable when groups of people are exposed to harsher conditions, for example the event that gave rise to Egypt itself was a great drought that the first known pharaoh conquered with canals off the Nile, single handedly unifying upper and lower egypt and becoming the first pharaoh of greater egypt. The tons of water, fruit and prey that forrests offer just don't seem to drive innovation as much or in the same way that harsher environments do.
