  • You just get started. Its part of the reason I’ve always preferred either forums or fark/ digg/ reddit/ lemmy style conversations.

    Also, writing is a skill. You get better at it with time. Its like how a TV show host can just ‘riff’ on a topic. I think responding to comments has definitely improved my ability to write in particular style (engaging/ proactive/ enthusiastic, whatever.).

    It also helps to be familiar with markdown, as good formatting makes the writing more satisfying.











  • Almost assuredly not, but we know so little about abiogenisis, its entirely plausible to consider that there may have been multiple origins of life on earth. The nature of cellularization, and DNA first versus RNA first models for life (or perhaps even some other “3rd” biomolecule? maybe surface level interactions on clay?), or even RNA only models. It may well be that there are other sources for abiogensis that are extraterrestrial, but that doesn’t overcome things like the concentration dilemma (you need some biophysical process to concentration “enough” of these interesting biomolecules to do meaningful stuff).

    So extra terrestrial things that stand on legs and have heads and eyes? Almost assuredly not. But it may well be that we’ve been repeatedly (or continuously) colonized by extra-terrestrial bio-molecules. I still hold out for some missions to features like Pluto where there is obviously a kind of deep-ice geochemical cycle happening (freeze-thaw based on coming close/ further to the sun). In these cycles there might be opportunities for basic biomolecules to form and accumulate. Slam a big chunk of it into a planet that is at least cool enough to have liquid water, and a geochemical cycle, that might be all you need.
