This argument is well-presented, however, contains at least four unreasonable assumptions. I will discuss each of them one by one.

Assumption one is that there were comets stroke the Earth.

Assumption two is that the water vapor changed from comets when striking Earth could be retained in the atmosphere of Earth.

Assumption three is that this water vapor retained in the atmosphere could finally rain on the Earth.

Assumption four is that the water in Earth’s oceans all comes from comets rather than other possible alternatives.
