Look At What The Planets Were Like 3.8 Billion Years Ago
What were the planets like 3.8 million years ago? Have you any idea how long it took the solar system to become it today? As for the Earth, it took billions of years for it to become the Earth you know.
And all planets of the solar system took their time too!
Had some distant aliens observed the solar system in the past, they would have noticed the planets were all way hotter than they are today, and wouldn’t probably have bet any of their money on it to eventually host life one day.
