"How can life emanate from no life?"
Through a process collectively known by scientists as abiogenesis, as far as science is currently able to ascertain.
As for your curious allegation, I'm afraid no evidence exists to effectively or even plausibly refute the contemporary scientific consensus concerning naturally occurring abiogenesis. You're free to insist otherwise, but I really must insist that your position is completely unfalsifiable, and hence has no scientific merit of any kind. To assert that it's "impossible" to replicate the genesis of life from organic compounds is an unsubstantiated argument from ignorance; it may very well be that in twenty or thirty years, for instance, science will be able to synthesize self-replicating organisms from organic compounds thought to have arisen from Earth's early atmosphere. At the same time, it's potentially impossible because of the immense scales of time that may be required for such synthesis to occur under such circumstances. Furthermore, while it's certainly true that no established model exists to account for the formation of life from organic compounds, several plausible hypothetical models have been proposed and are being actively investigated. It's important to emphasize that modern hypotheses concerning abiogenesis are fairly new, and may become more or less credible as time goes on.
