Many of these are microorganisms like bacteria and they first formed in the seas.
There were no chimps 1 billion years ago. At that time all life was single celled organisms and rudimentary multicellular ones.
No, vertebra life has not existed for more than half a billion to a billion years ago. Dinosaurs first appeared about 230 million years ago and died out 65.5 million years ago.
Photosynthetic organisms, such as cyanobacteria, are believed to have appeared around 3.5 billion years ago. These early organisms played a crucial role in shaping Earth's atmosphere by producing oxygen as a byproduct of photosynthesis.
3.5 billion years ago
2 billion years ago, simple unicellular organisms such as bacteria and archaea were the dominant life forms on Earth. These organisms laid the foundation for more complex life forms to evolve over time.

2 billion years ago ... You Plato user huh....
The evolution of single-celled organisms is estimated to have occurred around 3.5 billion years ago, while the evolution of multicellular organisms is believed to have started around 600 million years ago. This means there was a gap of about 2.9 billion years between the evolution of single-celled and multicellular organisms.
86 billion years ago
Sciences say that the sun was formed 4,600,000 years ago
