Oh dear, another one of these threads goes from "god dunnit" to philosophical abstraction.
No one who is more secular in their outlook has basically said anything other than "scientific research has demonstrated that homochirality is possible after just a few iterations of an auto-catalytic reaction". There is no statement or conclusion one way or another about a deity, aside an inference that once again science fills a hole that some have previously decided to fill with a god of the gaps.
The only people coming to formal conclusions are those who wish to conclude that this part of chemistry reflects the influence of a deity.
Discussing the chemistry and the research around it is not about promoting some atheist agenda, it simply a reflection of what we find through the methodical application of the scientific method.
