Well, obviously if you start with premise A, then A is easy to prove... that's not really reverse engineering.
Reverse engineering is attempting to understand an existing, verifiable phenomenon by breaking it into component parts. This can be done with something like a device, which is (at least apparently) all present; with 18th century science, you might very well be able to understand the purpose of a television by taking it apart into components and charting out their functions.
In this case you're starting with CS crater chains as one piece of evidence. However, claiming that they are "weapons of war" presupposes an entire scenario which must include ETs with interplanetary flight, whose civilizations somehow fell to fighting and destroyed themselves. These conclusions have little other supporting evidence, and much of what exists can be interpreted in other ways, so this is a lot to assume from a line of craters, no matter how straight it is.
Now, if information was being controlled by an advanced civilization, I would think that they would be pretty good at it. For instance, if I wanted to hide my alien presence on the Earth, and a bunch of Inca dudes were carving my portrait on the side of their house, I might ask them to stop. It would be difficult to see why modern evidence of ETs would be suppressed, but ancient evidence would be a popular discussion topic in the media if the ETs were trying to hide their presence.
