How has the summer sun changed the world?

Without summer, people did not appear, the world had lost a wonder, and the war was not of such magnitude.

The general condition of many people in recent days is . resentment over the intense sunshine of the summer. With a temperature of 50 degrees Celsius, many people become so extreme that they are ready to "curse" , saying that the price of life without summer is how easy life is.

Summer is a tragedy, not fun anymore.

But in fact, summer has made many important contributions to the world. Rather, summer is one of the factors that make up human history, making the whole world change in really different ways.

1. Summer is the cause of life

Up to the present time, Earth is the only place in the whole universe to be recognized for life. Life here is even a lot of things, enough to create a huge, diverse ecosystem.

But what does that have to do with summer? In fact, summer is the reason why we and all other animals appear.

Why? Let's return to the time of 4.5 billion years ago. The earth was very different then: hot, the surface temperature was up to 400 degrees Celsius, and of course there was no life. The reason is that the Earth's axis forms a perpendicular line to the orbit around the Sun - that is, the equatorial area directly captures all the heat from that great fireball.

Giant asteroids change everything.

It is also the time when the Earth is making "cannon bullets" for thousands, tens of thousands of meteors rushing into. Then, a giant-sized celestial body rushed in, creating the most powerful collision in history, so much so that a piece of the Earth detached, forming our Moon today.

But the impact of the collision is not only that. The Earth's axis after the event also tilts 23.5 degrees, and so the Sun is more evenly distributed, helping the Earth's climate to be mild with four distinct seasons in the year.

Season of supporting crops to create biodiversity.

Season of supporting crops to create biodiversity. In particular, summer is the time when life is the strongest, so it can be said that we are here thanks to the summer.

2. The Great Pyramid of Giza was built thanks to summer

The Great Pyramid of Giza is the first pyramid of Egypt. Built from the 2500s BC, Giza is still the tallest pyramid and today is considered one of the wonders of the world.

The Great Pyramid of Giza is the first pyramid of Egypt.

But to know that Giza is made up of about 6 million tons of granite, not to mention millions of other common stones. The problem is that this source of stone is taken from a mountain, nearly 13km from the construction site. And remember, modern machinery or technology at that time was not born, so transporting these stones was a very hopeless job.

However, the Egyptians still do it. All thanks to the genius minds of ancient Egyptian engineers, and the summer thanks.

Summer is a hurricane season - this is known to many people. The storms born in the Indian Ocean will blow to the West and create rain. This rainfall when coming to Egypt will have to be poured somewhere."Somewhere" here is the Nile.

Rain caused by storms in the summer creates floods, which usually occur in June every year. Flooding with the Egyptians was not a disaster, but like a gift of nature because the silt left the land more fertile.

By the time the fields were submerged in the sea of ​​water, the Egyptians were . more free to concentrate their resources on construction. But more importantly, the flood caused the river water to rise from the quarry area, overflowing towards the pyramid construction area. So the Egyptians suddenly had two choices: either to drag stones with human strength, or to drop stones along rafts downstream . Of course, they choose option 2.

According to historical documents, ancient Egyptians forced stone to the bottom of the raft, then waited for the flash flood to push the boat away. Thus, every day the Egyptians could transfer 3,000 stones weighing tens of tons, thereby shortening the time to build the Great Pyramid to about 20 years.

3. Summer is the source of war

The way people fight today actually originates from 50,000 years ago.

During the Stone Age, war was very small, extremely small. The reason is simply because fighting doesn't work. But in this age of working with survival, it is synonymous with self-destruction.

Society develops, and people have a great amount of manpower to start the war.

Then when people know how to cultivate, it is also easier for them to breathe. Society develops, and people have a great amount of manpower to start the war.

The reason that triggered a war was so much. But you know, the wars are almost always in the summer.

Why? Because the soldiers at the beginning were also farmers. Spring is a growing season, autumn is a harvest time. Winter is too harsh, so there's only summer left . to fight.

Today's wars are deeply rooted because . summer.

Over the summer, war has gradually changed. People fight more professionally, create armies, tactics, weapons . It can be said that it is summer that causes people to wage war because . it's too free.
