4 billion years ago, there were three Earths in the solar system? Scientists have discovered that the birth of human beings is an unrepeatable miracle!
The earth is the only planet where life is born in the entire universe. Humans continue to explore the universe and try to receive signals from extraterrestrial civilizations, but no signs of life have been found on other planets. Could it be that the Earth is the only planet in the universe that harbors life? If so, isn't Earth too lonely? But if other intelligent life exists in the universe, where would they be? We know that life can thrive as long as there is liquid water, moderate temperatures, an atmosphere, and sunlight. Interestingly, scientists found that there were "three earths" in the solar system 4 billion years ago! Then why are we the only ones left? Please look down.

On the 17th chromosome of the human body, there is God's prohibition, and there is no prohibition that human beings can grow into giants
do you know? The character, height, and length of a person in this life are actually predestined from birth. Human genes control everything about human beings, and also constrain human growth and development. Some people are born smart, some people are born tall. When scientists were conducting genetic research, they found that there is a prohibition left by God on chromosome 17 of the human body. This prohibition is used to restrict human growth.

In the past, there have been frequent claims of the discovery of suspected prehistoric civilizations, the most notable of which would be a two-billion-year-old nuclear reactor.

10 billion times harder than steel
From a microscopic point of view, the objects we normally see are actually made up of a large number of atoms, and the hardness of the objects varies greatly depending on the type of atom and the way it is bonded, for example, a diamond is made up entirely of carbon atoms, and the way it is bonded is that each carbon atom is bonded to the four carbon atoms next to it through covalent bonds, thus forming a crystal structure like the one shown below.
