I will prove to you that God exists

[Nay_Sayer]

It's worth observing that ants create structures which, in their particularity, aren't natural in the sense that the laws of nature in and of themselves create said structures.  But neither is the structure the result of any planning or design.  They are emergent as the regularity of ant behavior, applied to specific environments, creates the particular and specific structure.  Not that one needs additional examples over and above the fact that naturally occurring phenomena present the appearance of design which is only negated when the causal order which resulted in that appearance is understood.  This is one of the reasons the argument from design is so underwhelming.  We know from experience that an appearance of design is not reliably indicative of design.  Only by arguing from a false dichotomy that if the cause of the appearance is not explained naturally, then a non-natural explanation is the only alternative.  Which of course completely ignores other possibilities such as unknown causal narratives or hypotheses.

They usually obfuscate what they mean by plan, designer, et al by vaguely gesturing at the universe but also being very specific to things we observe on Earth.
