For example, a day on Earth was close to 6 hours when it first formed. The tides of the moon slowed the Earth down. A day that is 4 times quicker would produce storms that are 4 times more powerful because it is the rotation of the Earth that causes storm cells to spin. That means a storm with winds that are 150 km per hour now would be 600 km an hour on old Earth. The moon literally made it easier for us to live.
When the moon first formed it was close to the Earth so it would have appeared 15 times bigger than it does today and it had oceans of magma so it would have appeared a glowing red colour. It must have been an amazing sight to see.
I often wonder what old Earth looked like with a new crater free incandescent moon filling the sky.
