Water covers over 70% of the Earth, cycling from the oceans and rivers to the clouds and back again. It even makes up about 60% of our bodies. But in the rest of the solar system, liquid water is almost impossible to find. So how did our planet end up with so much of this substance? And where did it come from? Zachary Metz outlines the ancient origins of water on Earth. Lesson by Zachary Metz

Do you know that for 70% of worlds water to land on earth, it would mean that the asteroids would have to be 20 to 50 time bigger than the actual size of our world which it means that if it came from asteroids, the world we know of is millions of times bigger than the world we think but It doesnt make sense since in a car shaped asteroid you can find water to only fill two to three bottles at most since it is mostly rocky but the closest theory icy asteroids if that could happen without melting before hitti g the ground or atmosphere. Its just impossible the this much water came from rocky asteroids since it would totally get destroyed in the first hit and icy asteroids could be possible but yet again its unlikely to come from outside of earth since humans have disvovered lakes way beneath the ground, it must come from within the world somehow and no one can ever know the truest root from where it comes from.

I can say it's because of the heat the sun. Very good example is cooking rice. Whenever I cook rice, of course the cover of the casserole as the atmosphere; the fire is the sun. As the temperature rise, you can see a moisture called condensation. And that's the rain, the water.

My guess would be like the giant impact theory of moon: A cosmic event that came at the right time when the earth had cooled enough and had generated a magnetic field, I dunno.

I don't think so! Asteroid bring water? why doesn't the moon have water than? Even scientists speculate it, the water comes from somewhere nobody exactly knows where or when
