The point wasn’t that what I came up with is necessarily likely or possible though, just that maybe it will turn out there's life, i.e. some self-reproducing evolving thing that doesn't store its instructions for self-reproduction in a molecule in a solution. As for physical processes we haven't heard of, I was thinking of things that's not chemistry, but could reproduce some patterns. Some examples we have in technology is photography or photolithography.
