Yes, right. Right here on Earth, we have living creatures that can survive temperatures above 100 degrees Centigrade (the boiling point of water), and living creatures that contain no DNA. (You might question whether prions are really "living creatures", but at least they can reproduce. Prions produce the mad cow disease.)
So who knows what surprises await outside the Earth. It is to be hoped they look close enough. Just looking for DNA might not be enough: it is conceivable, perhaps even likely, that life without DNA exists.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
