So what evidence must we explain? Here it is:

The Mercury ice
A vast amount of it
Organic material in the Mercury ice, that did not form on Mercury.

So: several comets, and maybe some water-rich asteroids too, fell onto Mercury’s north and south poles. And those comets and asteroids held organic matter. This begs another question: where did objects like these come from?

For that we have two competing explanations:
Panspermia

Panspermia (from the Greek pas, pasa, pan all, every, etc., and sperma a seed) means “seeding everywhere.” According to the panspermia theory, comets and asteroids, or at least a significant portion of them, hold the stuff of life along with their water. Some of these fell to earth, and we are the by-product. Maybe some of the rest fell to Mercury (and the Moon, and Mars).

But this begs the question of where the stuff of life came from, and how it could cross space, subject to cold and radiation, and still “seed” the Earth. Indeed, most evolutionists don’t believe this. They believe in abiogenesis, the notion that life arose from non-life. But abiogenesis could not possibly explain the organic layer on the Mercury ice. (The primordial soup would be far too cold.)
The Hydroplate Theory

The Hydroplate Theory is Walt Brown’s theory of the Global Flood. According to it, half of today’s ocean water lay deep underground—very deep. Ten miles deep. About 4400 years ago, the ten-mile-thick crust cracked open and let all that water out. It came out with enough force to throw vast amounts of water, rock and mud – one percent of the total weight of the Earth – into space. That water, rock and mud persist as comets, asteroids, and meteoroids.

Brown explains how comets formed in the micro-gravity of space. (Even a hand-sized rock, far enough away from any planet or moon, can become an orbital primary and make other, lighter-weight objects fall into it.) He also shows that such comets would fly off from earth in all directions. That’s why comets today have orbits going off in all directions. And Brown defies anyone to explain the Mercury ice (or the lunar or Martian ice, either) by any other theory of where comets came from. (Brown also knew about the Mercury ice twenty years ago, when NASA first suggested it.)

And the organic matter? Anything from germs to shrubs, that the escaping water, rock and mud carried with it. In fact, Lawrence, in the Science paper, says the ice melted when it crashed, then re-froze, with the dark organic layer on top. According to the First Law of Thermodynamics, it could do nothing else.

Brown confirmed today that the Mercury ice confirms his theory. That means the Mercury ice confirms creation, not abiogenesis or panspermia, as the origin of life.
