Increased Greenhouse effect apex
No. The Moon was probably formed in a titanic collision between the proto-Earth and another smaller planet perhaps as large as Mars, when the solar system was still very young and chaotic, about 4 billion years ago. There was no life there. However, if there HAD been any life on Earth, a collision of that magnitude would certainly have exterminated it all, and entirely re-shaped our planet. Probably not a single trace of the original crust of the Earth would have survived.

You are more likely to find mold or mildew growing in your refrigerator. It could be caused by rotting food stains or rotting water.
Brachiopods were marine organisms that thrived primarily during the Paleozoic Era, particularly in the Cambrian and Devonian periods. During this time, trilobites were also abundant in the oceans and likely coexisted with brachiopods. Additionally, early fish, such as jawless fish, were present during this period, further indicating a diverse marine ecosystem alongside brachiopods.
It is not known for certain but it is likely that a massive asteroid impact caused the planets axis rotation to tilt.
Significant volcanic activity or a sudden increase in greenhouse gases, such as carbon dioxide, most likely caused the giant ice caps of the Paleozoic era to melt. These events would have led to a rapid warming of the climate, resulting in the melting of the ice caps.
A significant increase in greenhouse gases, such as CO2, and a rise in global temperatures would have most likely caused the giant ice caps of the Paleozoic era to melt. This could have been triggered by volcanic activity releasing large amounts of CO2 or natural climate cycles.
The melting of the giant ice caps in the Paleozoic era was likely caused by a combination of natural processes such as changes in Earth's orbit, volcanic activity releasing greenhouse gases, and plate tectonics shifting continents. These factors led to a warming of the climate and the eventual melting of the ice caps.
During the Paleozoic era, the Earth experienced significant fluctuations in climate due to factors such as variations in the Earth's orbit, volcanic activity, and changes in greenhouse gas levels. These fluctuations likely led to the melting of the giant ice caps that existed at that time.
There were major asteroid impacts.
The first land-dwelling organisms, which were likely plants and fungi, appeared during the Paleozoic Era. This transition from aquatic to terrestrial environments occurred around 460 million years ago during the Ordovician period.

Changes in the Earth's orbit and axis tilt, increased volcanic activity releasing greenhouse gases, and decreased albedo due to the removal of vegetation cover could have contributed to the melting of the giant ice caps that existed in the Paleozoic era.
Extinction is most likely to be caused by environmental conditions. Dramatic changes to the climate can mean that species are no longer adapted to survive.
No.... It depends on what virus caused it but most likely no.
