It rained a little today, on and off.
There was time in Earth’s history when it rained for eons.
Here is an excerpt from a book I’m reading:
For a few million years our planet had rings, like Saturn. Eventually, the rings coalesced to create another new world – the Moon. All this happened approximately 4,600,000,000 (4.6 billion) years ago.
Millions more years passed. The day came when the Earth had cooled enough for the water vapor in the atmosphere to condense and fall as rain. It rained for millions of years, long enough to create the first oceans. And oceans were all there were; there was no land. The Earth, once a ball of fire, had become a world of water. Not that things were any calmer. In those days the Earth spun faster on its axis than it does today. The new Moon loomed close above the black horizon. Each incoming tide was a tsunami.
