The presence of hot, nourishing soup on Mars would certainly bolster the argument that life once existed there.
One sharp-eyed Mars enthusiast writing on the Unmanned Spaceflight message board spotted this kitchen instrument sticking out of the bedrock in a recent panorama from the Mars Curiosity Rover. Sadly for everyone who wanted to sample some Martian Gumbo, the reason this spoon is sticking out of the bedrock is that it is part of the bedrock.
It's a ventifact, which is something created by wind (as opposed to an artifact, something created through an art or craft). Specifically, the erosion is caused by sand being blown by wind—like a very slow sandblaster. Water is the dominant erosive force on Earth, so ventifacts here are mostly found in dry, sandy areas. On Mars, which is one big desert, they're pretty common. Of course, we're never going to stop people from seeing faces, women, or kitchen instruments on Mars, so why bother trying?
