After the sun was born, during the Hadean era (4.5 BYA), all the matter at the furthest end of the spinning disk began to clump together, which is the seedling that formed new planets. The more they clump together, the bigger and more circular they get. All the clumps closer to the sun were the rocky materials that formed the earth.

Science:

The earth was formed by gases (hydrogen sulfide, methane, and carbon dioxide), dust, etc and later turned into a rock. It then started pulling in more rocks dust and gasses and formed a ball, which then became a planet

4.5 BYA, Asteroids and comets would continuously hit the early Earth, but suddenly a planet the size of Mars called Theia fell straight into it. Massive pieces of matter were flung throughout Earth's orbit by this collision, and when gravity pulled them together, the moon was formed.

Science:

The collision threw huge chunks of matter around the earth's orbit, and gravity-bound them together, which is related to psychics

3.8 billion years ago, the earth had no water; it was just a hot ball, but some time later, the earth cooled down enough for water to condense. The very first ocean covered the earth, making it into a waterworld.

Science:

most of Earth's water came from meteoroids, as they held water droplets inside them

(Asteroids become known as meteors when they collide with a planet) that struck the Earth.

H2O is essential for a living organism to function, and since Earth had this much water life first appeared 3.7 billion years ago, these were microscopic organisms called prokaryotes.

Science:

Now that the earth had a lot of water (H20), which is essential for a living organism, A living organism called prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles

3.3 billion years ago. Earth didn't stay as a watery land for long; soon, as more land rose from the ocean, the first craton appeared on Earth

2.4 billion years ago, the cyanobacteria evolved, which became our first photosynthesizer. We now have an oxygen producer, which makes the earth's atmosphere more hospitable.

Science:

A group of ancient photosynthetic microorganisms known as cyanobacteria, or blue-green algae, are found in most inland waters and can have a significant impact on the health of the water and the operation of aquatic ecosystems. They come in 150 genera, with roughly 2000 species that vary greatly in size and form.

2 billion years ago, as the atmosphere was changing rapidly, the continents were moving as well, creating a new supercontinent called Rodinia, which grew very fast and was the largest supercontinent on earth

Science:

Scientists called the first ice age the Pleistocene Ice Age and they believe it has been going on for 2.5 million years.

1.1 billion years ago, as the atmosphere was changing rapidly, the continents were moving as well, creating a new supercontinent called Rodinia, which grew very fast and was the largest supercontinent on earth

650 MYA, The supercontinent Rodinia broke apart, because of the activity of mantle plumes or of a mantle superplume beneath the supercontinent. A new supercontinent was created which was called Pannotia.

540 million years ago, during the Paleozoic era, there was a new explosion of life, which is known as the Cambrian explosion. The types of animals that evolved during this period were very unusual and had hard body parts. The most unusual animal was the alien-looking trilobite.

Science:

the extraordinary beginning of the Cambrian Period, between 541 million and around 530 million years ago, when creatures first emerged.
