laodan rated 8 months ago- Cosmic Dust Forms Inorganic Life in The National Geographic by Scott Norris
A new study suggests that under certain conditions cosmic dust and plasma can organize into stable, helical-shaped structures that resemble inorganic life-forms. Using computer simulations, a team led by Vadim Tsytovich, of Russia's General Physics Institute in Moscow, found that under certain conditions dust and plasma can organize into stable, helix-shaped structures resembling DNA. While the structures exhibit none of the complex chemistry associated with even the simplest forms of life on Earth, they appear to at least mimic some the basic processes associated with living systems, the team said. For example, the helical strands were sometimes capable of reproducing by splitting and reassembling into two identical copies. The structures also exhibited a kind of evolution, according to the researchers. Structural changes that took place in the strands were passed from one "generation" to the next, the researchers said. As conditions changed, only the most stable configurations were able to persist.

Yes life emerges as the result of chain of complex chemical reactions flowing in particular conditions. What's the problem with that? I have none but why do humans experience such difficulties in accepting that fact?
