HPT explains what (Catastrophic) PT cannot.
Plate tectonics cannot explain the average of a mile deep sediments across the globe.
PT cannot explain seashells on top of mountains.
PT cannot explain asteroids, meteorites, meteors, comets, water on Mars, etc.
PT cannot explain why the near side of the moon looks like it's been pummeled, whereas the far side is fairly clean in comparison.
PT cannot explain why 90% of Earth's radioactivity is in the continental crust of the earth.
And it's not for lack of trying, it's just not possible to explain those things with PT.
But it is with HPT:
Mile deep sediments across the globe? Seashells on the tops of mountains? result of a global flood.
Origin of asteroids, meteorites, meteors, comets, water on Mars, etc.? Result of the "Fountains of the Great Deep breaking forth."
Near side of the moon pummeled? debris launched from the "Fountains of the Great Deep impacted the moon on the near side, and debris that couldn't escape Earth's orbit came back and hit the far side of the moon, though doing much less damage.
Radioactivity in the crust?
