Why not just answer the question?

You made the claim that this was a "rare" and "interesting" formation. I want to know how you arrived at that conclusion. Throwing the question back at me is an obvious "dodge".

It is NOT "closed minded" to demand credible evidence for extraordinary claims particularly on this board.

If the only "evidence" for artificiality is "to me it looks like an alien spaceship", then I can understand why you don't want to continue this discussion.
