The origin of life and the origin of the universe are among the most important problems of science and they might be inextricably linked. Hydro-gravitational-dynamics (HGD) cosmology predicts hydrogen-helium gas planets in clumps as the dark matter of galaxies, with millions of planets per star. This unexpected prediction is supported by quasar microlensing of a galaxy and a flood of new data from space telescopes. Supernovae from stellar over-accretion of planets produce the chemicals (C, N, O, P etc.) and abundant liquid water domains required for first life and the means for wide scattering of life prototypes. The first life likely occurred promptly following the plasma to gas transition 300,000 years after the big bang while the planets were still warm, and interchanges of material between planets constituted essentially a cosmological primordial soup. Images from optical, radio, and infrared space telescopes suggest life on Earth was neither first nor inevitable.
By ΛCDMHC, (the standard cosmological model) it is highly improbable that life could be widely transferred in the cosmos, and impossible for life to begin. The extreme complexity of the simplest living microorganism suggests spontaneous creation (abiogenesis) is impossible without templates.
The scientific version is that conditions had to be "just perfect" for life on Earth to exist as it does.
I don't know if life on Earth originated on Earth or not. But I do like the theory that we are gaining not only material, but genetic material from space, in the form of viruses and other micro-organisms. They may not have been the seeds of life here, but they may help influence its development. Given the discovery of so many extremophiles and the discovery that, contrary to prior belief, the universe is soaking wet (relatively speaking), I don't think the existence of life forms and/or genetic material, pervasive in the dust and debris of the universe is that far fetched.
Weathered mica crystals look something like a book that has been left out in the rain and they have a lot of surface area where organic chemicals and minerals can arrange themselves over a long period of time on an undisturbed surface.
