Thank you JR for the explanation of the hydroplate (HP) theory.
I did actually watch (much of) the video, so I recognise that your description comes from the hydroplate guy, who you tell me is a Phd and an engineer.
I want to tell you why the theory just will not fly, is a damp squib, and why the guy is an idiot, so that you can move on to believing something more possible and FACTual.
At the heart of the HP theory is the idea that there was water in the earth, and earth convulsed and squeezed this water out of the crust at escape velocity, so that water (and rock) shot up with such force that it escaped earth's gravity, still had enough velocity to keep on going and throw rocks on the moon such that they formed craters on the near side of the moon. Have I got the theory right?
Here are the problems with the theory...
To escape earth's pull, each drop and rock has to be ejected at the escape velocity from Earth which is about 11.186 km/s (6.951 mi/s; 40,270 km/h; 25,020 mph) at the surface. This is mach 33.
A water jet cutter can, with all its technology get a jet of water up to mach 4 only.
And even if you pointed a water jet cutter up to the sky, the drops would not go far because they would bleed off momentum so quickly due to air friction. Water under this pressure and speed would be hot and would vaporise. If water ever reached space, it would evaporate in the vacuum of space.
And with all this high pressure ejection, poor Noah and the animals would be subjected to the tidal waves, and debris falling back which does not make it into space.
There is no chance that water or even rocks ejected from earth could make it to the moon, and then, slow down and fall back on the far side. To do so they would have to have been ejected at escape velocity plus plus - which even the explosion from a super volcano cannot do. And a super volcano would destroy most life on earth and the tidal waves would sink the ark.
This is a half-baked, pie-in-the-sky piece of non-science, you would do well to reject.
