[Alan V]

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.

So dinosaurs lived on earth for over 500 times longer than people. Cool.
