How did life start? No creationists please

[Walking Void]

Lately it seems that there have been breakthroughs along this line of investigation.

Lawrence Livermore scientist Nir Goldman and University of Ontario Institute of Technology colleague Isaac Tamblyn (a former LLNL postdoc) found that icy comets that crashed into Earth millions of years ago could have produced life building organic compounds, including the building blocks of proteins and nucleobases pairs of DNA and RNA.

Comets contain a variety of simple molecules, such as water, ammonia, methanol and carbon dioxide, and an impact event with a planetary surface would provide an abundant supply of energy to drive chemical reactions.

Again, the amount of energy released in an impact is mind-blowing.

Of course this all drives the creatards up a wall but then, what doesn't?

It can also explain the appalling difference in depth between the ocean and the surface. In different words why the earth's surface is shaped the way it it. I was wondering if comets had much involvement in tectonic plate movement but I am not an expert in astrophysics and space science.

But I adore vacuums.

As for where We came from, I prefer to agree with uncertain cell growth independent from aliens unless, even at billions of years ago, aliens may have cultered some cells on earth... but it sounds too destined, too complex for something so far into the past.
