IMO, too many anomalies are written off as "natural" and I think part of it is due to people advancing theories that have gained even slight acceptance. They in turn become solidified as Holy Writ and all efforts are directed to defending that theory, to the point of ruining peoples' careers. Then the major protagonist dies and those who no longer have to fear of being ostracized as heretics, come up with an alternative, and usually a better interpretation.

Some wag, familiar with that dark side of science, opined that science progresses from funeral to funeral.

What I do not understand is the pressing need for an explanation, the ‘thing’ is there and nothing changes the object regardless how mundane or fantastic the theory. We are looking at the results of some so far inexplicable phenomena which have been there for possibly thousands of years. If they remain a mystery for another century, so what?

Google Earth is showing us how much we have not been able to see before.

Patterns similar to this exist in dry river beds in Western Kenya. Initially they were dug by people looking for water. Later, gold was discovered and the local tribes dung down to the gravel/bedrock looking for gold.
