Earth made water.. right.. and a big explosion made the earth? How stupid do you think we all are?

So the theory explained here is that Hydrogen mixed with the Oxygen in the melted rock (magma) of earth, under extremely high pressure to create our earth specific flavor of H2O (appropriate amount of trace minerals and deuterium).
Am I reading that correctly?

Life began in the Ocean, but why did civilization begin on land? Is it because of fire? But I wonder if a different kind of civilization could have emerged

Maybe some of Earth's oceans came from its rings collapsing (not kidding)
