Alien life claim ignites scientific debate

I read about these NASA researchers that claim to have found evidence of alien life. This is suppose to spark many heated debates and fight over whether its true or not within the next few days and weeks. The NASA scientist says he found bacteria like the ones on earth that "hitched a ride on a meteor"....I think that if this turns out to actually be alien life then it wold be pretty cool. Hopefully if we find more of them then they will be friendly and not try to kill us like in all the movies there are.
