🧵 REPLYING TO @luismbat (Luis Batalha 🇵🇹🇺🇸):
┌─ "Imagine an alien watching Earth from the Moon with a telescope.
For thousands of years: no signs of humans - just forests, oceans, clouds.
Then around 1700 (~300 years ago), cities, roads, and lights appear.
Exponential progress is invisible... until it’s not."

💬 ELON'S REPLY:
@luismbat True.
If aliens came to Earth before the invention of writing ~5500 years ago and tried their hardest to explain spaceships & supernovas, they would fail.
