Open AI answer to my question "how old is life on earth?"

how old is life on earth ?

ChatGPT said:
Life on Earth is estimated to be about 3.5 to 4 billion years old.
Here's the timeline in a nutshell:
  • 🌍 Earth formed: ~4.54 billion years ago
  • 🧫 Earliest evidence of life: ~3.5 to 3.8 billion years ago
    • These were simple, single-celled organisms like bacteria
  • 🌿 Complex life (multicellular organisms): ~600 million years ago
  • 🦖 Dinosaurs: ~230 to 66 million years ago
  • 🧠 Humans (Homo sapiens): ~300,000 years ago
Life started very simply and gradually evolved over billions of years into the complexity we see today.
