Every colandar is really a bowl

Among the geological wonders of New Zealand, the Moeraki Boulders (see Wikipedia article) are surprisingly spherical in shape.

See this Youtube video - one of many but it has nice music.



Some regard these remarkable stones as proof of the existence of a god - presumably their own particular God.

Geologists who are aware of similar septarian concretions all around the world have theories about how they were created, but no definite conclusions.  As it says on the Wikipedia article linked in this paragraph:

A number of mechanisms, i.e. the dehydration of clay-rich, gel-rich, or organic-rich cores; shrinkage of the concretion's center; expansion of gases produced by the decay of organic matter; brittle fracturing or shrinkage of the concretion interior by either earthquakes or compaction; and others, have been proposed for the formation of septaria. At this time, it is uncertain, which, if any, of these and other proposed mechanisms is responsible for the formation of septaria in septarian concretions.

Claiming that this gap in our knowledge proves the existence of god is a logical fallacy.  Just because there is a gap, it doesn't mean that there has to be something to fill it.  Here are some gaps . . .

Every colander is really a bowl (with gaps)

Would you ever think of calling a colander a bowl?  It is the gaps that make it useful.
