There were some proof of actual ice ,according to a source " Researchers were able to prove the soil had ice in it because it melted in the oven at 32 degrees Fahrenheit (0 Celsius) — the melting point of ice & dash; and released water molecules. Plans called for baking the soil at even higher temperatures next week to sniff for carbon-based compound ".Those right there are very Earth like traits, and since humans live on earth they may be able to possibly live on a different in this case the other planet would be Mars.

"By melting icy soil in one of its lab instruments, the robot confirmed the presence of frozen water lurking below the Martian permafrost. Until now, evidence of ice in Mars' north pole
