"What about the chemistry of 'black smokers' and geothermal vents in the deep oceans? "

It's going to take a lot of tap dancing to get me to believe DNA spontaneously came together. Black Smokers not withstanding.

Good thing that's not on the agenda, then. All contemporary theories of any passing scientific gravity hold that life evolved gradually, from it's beginnings through the present moment.

DNA came much later. RNA (or possibly a simpler RNA analogue) came first.

The process of abiogenesis had many steps that must be explained, and these holes in our knowledge are slowly (but surely) being filled. So those of us who are unafraid of the science see each new discovery & say, "fascinating, good work!" While you who are afraid of us finding how life got started get another chance to say "yeah but look at all the problems that remain over here!"

Interesting how one side of the debate always ends up cheering each new discovery or intriguing theory, while the other side always gets nervous at new discoveries.

Well timed pic!

I just find it facinating to have such a biosphere in such adverse conditions. I would think that the protiens organized before DNA/RNA started getting into the business.
