The Plastic Industry on Mars

Well folks, I've worked in the plastic industry for 35 years , starting as a machine operator, then I went to sales, and finally ended up my career as a tooling engineer.
Now working around plastic extruders for 35 years, I know them pretty much backwards and forward. You can't imagine how far my jaw dropped when I saw the following image. Here there was a plastic extruder sitting on Mars. Now in other locations in the full image you see piled up piping, and not only that, I've seen skids of pipe piled up all over in other images. When you look you'll see a hopper, and the barrel cover, and what appears to be a tubing die mounted on the front.
Now it's not a very pleasant image because it looks like the building has just been blown to smithereens by a tank sitting to the right of the picture. There are several dead bodies lying around on the floor. It appears there were several different sized humanoids working there also. Take a look and see if you can see what I see. There looks to be a couple other extruders farther back, but the're more covered up.

To NASA:
Dear NASA, It appears they're making plastic pipe on Mars, which means they probably have oil, which means there was organic life there for many, many millenniums. Just thought I'd help . Also have you located any water yet, and just who are you working for? We are waiting for your answers.
Thank,
Your average American taxpayer.
