Literally that would have been about four billion years ago when the earth was still a molten mass of iron and magma, completely liquid with a temperature of many thousands of degrees.

The Earth's "Snowball Earth" period occurred approximately 650 million years ago during the Cryogenian period. This was a time when the planet experienced multiple episodes of global glaciation, with much of the Earth's surface covered in ice.
The Cretaceous period occurred approximately 145 to 66 million years ago.
The highest oxygen level in Earth's history occurred during the Carboniferous Period, approximately 300-360 million years ago. This period is often referred to as the "golden age of insects" due to the size and diversity of insect species during this time.
The Carboniferous is considered to have started 354 million years ago and ended 290 million years ago.
The hottest 10 years on Earth have occurred within the past two decades, specifically from 2005 to the present day. This trend highlights the ongoing impact of climate change on global temperatures.

AnswerThe last ten years have been the hottest since accurate records began.There have been hotter periods in the past, but species had time to adapt. The present rate of climate warming seems to be the fastest ever.
Globally, most of the top 10 hottest years have occurred in the last 15 years.
The five mass extinctions that occurred in Earth's history took place during the Ordovician period (about 445 million years ago), the Devonian period (about 375 million years ago), the Permian period (about 251 million years ago), the Triassic period (about 200 million years ago), and the Cretaceous period (about 66 million years ago).
The Earth's "Snowball Earth" period occurred approximately 650 million years ago during the Cryogenian period. This was a time when the planet experienced multiple episodes of global glaciation, with much of the Earth's surface covered in ice.
the orbital period of Saturn in earth years are 89years
The orbital period of Jupiter is about 11.9 Earth years. This means it takes Jupiter approximately 11.9 Earth years to complete one orbit around the Sun.
The appearance of the most complex and the greatest diversity of organisms on Earth occurred during the Cambrian Period, around 541 million years ago. This period is known as the "Cambrian Explosion" due to the rapid diversification of multicellular life forms.
Red stars are the coolest. They are usually between 3,000-6,000 degrees Fahrenheit. They include Proxima Centauri (4.2 light-years from Earth) and Betelgeuse (350-650 light-years from Earth). The cooler and smaller the star, the longer it lives. Blue stars are the hottest, but the LBV types, such as Eta Carinae (7,500 light-years from Earth) and R136a1 (163,000 light-years from Earth) are the hottest and heaviest in the universe. They could range temperatures from 50,000-100,000 degrees Fahrenheit.
The Devonian Period lasted for about 63 milion years. It occurred 354-417 million years ago.
The Cretaceous period occurred approximately 145 to 66 million years ago.
