Could Unexplained Ice Falls Be From Comets?

Our home, Planet Earth, is a very wet place. In contrast, our neighbor, Mars, is a desert.

Three-quarters of Earth's surface is covered by water. It's mainly in liquid form, though ice exists over the northern and southern polar oceans and water vapor is present in the atmosphere.

Being 93 million miles from the sun, conditions are such that water "sticks" to our planet. All three phases can coexist, so water remains a prominent feature.

Dating of meteorites indicate that our solar system is about 4.6 billions years old. The older sedimentary rocks, formed through processes requiring water, are about 3.9 million years old.

Water must have been present at least that long ago then. It is not clear where this water came from, but the traditional view has been that it was a byproduct of planetary cooling, our seas resulting from the condensation of water vapor originating in the rocks of the Earth's crust.

In the last decade, some new and radically different ideas have emerged from the scientific community, particularly from University of Iowa astrophysicist Louis A. Frank.

I've heard this theory before, that ice, particularly the polar caps could've been the result of asteroids hitting the earth, or other planets at the formation of the Universe. Have you heard this before, and if so do you think it has much credibility?

a scientist being interviewed on coast2coast AM
-maybe it was wednesday night?-
stated that super novas
produce copious ammounts of Hydrogen & Oxygen
along with other elements...

(see article posted, -> molecular cloud & H2O spectrograph)

which brings us back to: www.panspermia. -> a theory that falls in & out of favor!...which your post alludes to, in citing 'water' as a 'universal solvent' and medium
for carbon based molecules to grow.
