Here's where you have to be careful if you want to approach something scientifically. The plumb at the end of your investigation should be to discover what is really there - even if it is a natural formation.

It is OK to have an initial opinion or a notion based on impressions, but to be scientific, you have to accept the possibility that the reality will be completely at odds with your belief.

This will allow you to bring in evidence that runs counter to your impressions. The simplest explanation for the shapes in Cydonia, based on all the information gathered from past missions and observations, as well as what is known about Mars today, is that the formations are completely natural.
