Days was shorter and less hours than today. 21 hours in 1 millions years ago = earth was spinning faster. A day = 6 hours after collusion. Huge tide moon gave us cause bit tides that hits the mountains and rocks causing them to mix and get minerals in water causing life. Tidal friction cause earth to slow down and days lasted longer. When nasa visits moon they leave flag and reflectors, then nasa shoot laser to reflector and see how long it takes then takes data. Each year the moon is moving away because it is taking longer for laser to reflect.
