We're in the realm of wild speculation here. But if I had to bet: the first lifeform will be fragile. Die on slight heat changes, not survive a trip off their planet and easily die in any kind of meteor scenario. But as I sad - it's a wild guess out of the blue.

Yeah. If I had to bet what the first extraterrestrial species we will find will be. Probably a primitive form of moss. Or a weirdo bacteria.
