Minor quibbles, which don't actually detract from your argument:

There is evidence that life might arise fairly easily, given the right
conditions. This is the so-called "early appearance of life
argument". See arXiv:astro-ph/0209385.

Endangerment of a species does not follow from a genetic
"bottleneck". Consider a beneficial mutation arising 70,000 years ago,
and rapidly increasing to 100% fixation within the human
population. The genetic data would point to us all being descended
from a single "Adam" or "Eve" at the time, and the number of
individuals whose descendants ultimately breed with Adam or Eve's
descendents. All other germ lines are eliminated from the population
by natural selection. Thus a genetic bottleneck. However, the breeding
population may have been any number - eg 1 million, hardly an
endangered species.
