[Blood of Tyrants]

If you can believe that living things came from non-living things, you can believe anything.

[Revelation 911]

interesting how some can believe an eyeball was selectively adapted from something that could not previously "see" in the narrow spectrum that is visible light, let alone create the optics and the sensory input required for it.

I personally wanted xray vision

Blood of Tyrants: "If you can believe that living things came from non-living things, you can believe anything."

But the distinctions between biology and organic chemistry are matters of definition, construct and convention.
So where, exactly, does complex chemistry end and simple life begin?
If we look around the natural world today, we can see examples of both, and some seemingly half one, half the other.

That complex organic chemistry can evolve naturally is observable, testable, confirmable and therefore indisputable.
That evolving natural organic chemistry will, under certain circumstances, "complexify" is also demonstrable.

Of course, how, exactly complex chemistry became simple life we don't yet fully know, but nothing discovered so far makes that impossible.
