We live in a little blue planet and we know that's it's big and blue but what's the age of our blue planet??
Our earth is pretty much old it's about one-third the age of our universe...and that's about 4.54 billion years and that's due to acreetion of the solar nebula.a nd during the early age of Earth our earth is hot red in colour due to mass volcanic mountains and eruptions with almost no Oxygen. the atmosphere and the oceans were created by the volcanic outgassing. And our blue planets little Neighbor was thought to be formed due to a faint impact by a large body.and as the time passed earth cooled and the vapour was cooled and water wereble to be in liquid form and the surface was Hardened as the molten lava cooled down
Earth during the early stage
In geochronology, time is generally measured in mya (megayears or million years ago), each unit representing the period of approximately 1,000,000 years in the past. The history of Earth is divided into four great eons, starting 4,540 mya with the formation of the planet. Each eon saw the most significant changes in Earth's composition, climate and life. Each eon is subsequently divided into eras, which in turn are divided into periods, which are further divided into epochs.
And the four eons are
# Hadean which was 4,540–4,000 mya
# Archean which was 4,000–2,500 mya
# Proterozoic which was of 2,500–541 mya
# Phanerozoic which was 541–present
Earth is often described as having had three atmospheres. The first atmosphere, captured from the solar nebula, was composed of light atmophile elements from the solar nebula, mostly hydrogen and helium. A combination of the solar wind and Earth's heat would have driven off this atmosphere, as a result of which the atmosphere is now depleted of these elements compared to cosmic abundances. After the impact which created the moon, the molten Earth released volatile gases; and later more gases were released by volcanoes, completing a second atmosphere rich in greenhouse gases but poor in oxygen.Finally, the third atmosphere, rich in oxygen, emerged when bacteria began to produce oxygen about 2.8 Ga.
And our planet undergoes many changes it had iceage for many several million years even though the heat from sun is increased the records show us that during that period earth had iceage from the beginning earth had four ages and during ice age the average temperature on earth was -70 to -65°c even the highest mountains were covered in ice.
But our earth has survived them all
Earth during iceage
And our earth had mass extinction periods the well known mass extinction was the last one which was the extinction of the great dinosaurs..and I
We humans continue the sane way we are going to lead the way to another great mass extinction.
First life on Earth came through abiogenesis(formation of life from non-living organisms) and the first were the single celled organism's and the organism is the great great archebacteria.
And a note earth was formed due to the above reasons not that God created it and humans and the life on Earth was formed and evolved through the favorable conditions........not God did all that......

Formation of due to huge Collison
And about the continents they are once all united bit due to massive shift if earth's tectonic plates they are all moved away.
