This topic is debated but here is the most likely cause:
Those organisms reproduced and created more organisms. Over time the organisms changed (due to the Earth changing).
The organisms reproduced with other organisms and created a new species. After millions of years, creatures like wolves and humans now exist. Hope I helped

The first single-celled organisms, like bacteria, are believed to have appeared around 3.5 billion years ago. These organisms are considered some of the earliest forms of life on Earth.
The single-celled organism that is most closely related to the first cell to exist on Earth is likely a type of archaea. Archaea are ancient single-celled microorganisms that are considered to be one of the earliest life forms on our planet. They share many genetic and biochemical similarities with the first cells that appeared on Earth.

The biosphere is defined as the living organisms on earth. As such, it began to evolve when the first organisms appeared. Currently, this is believed to have happened about 3.5 billion years ago.
The first life forms on Earth were likely single-celled organisms such as bacteria or archaea that appeared around 3.5 to 4 billion years ago. These simple organisms were the precursors to all life that followed.
The second organism that appeared on Earth was likely a simple single-celled organism, possibly a prokaryote such as a bacterium. This would have followed the appearance of the first organism, which was also likely a simple organism.
Who appeared on the earth first
Single cell prokaryotes first appeared perhaps 3.8 billion years ago.

Since we don't actually know which organism appeared first, there's no way of knowing what came second.
what do u mean whic appeared on earth
Read your science book chapter . It is on the first page.
The first organisms arose in the Precambrian era, which encompasses about 90% of Earth's history. This era began about 4.6 billion years ago and ended around 541 million years ago.
bacteria
A single celled organism.
Multicellular organisms first appeared during the Vendian period.
