Life On Other Galaxies?

I go to a weekly "worldviews"/biblestudy class. In it, one day, a question of "life on other galaxies" came up. Don't ask me how. Because I won't know the answer. Anyway, the guy that teaches it said he believes that there is not life on other galaxies due to the following verses: "For creation was subjected to futility, not willingly, but because of Him who sujected it in hope; because the creation itself also will be delivered from bondage of corruption into the glorious liberty of the children of God. For we know that the whole creation groans and labors with birth pains together until now." Okay, the italicized verse is talking about how creation suffers for Adam's sin. Emphasize whole creation. The teacher says that this would include other galaxies, and why should other galaxies suffer for something Adam did in this galaxy. Okay, I will go with that, but then I wonder why do people in this galaxy suffer for what Adam did? Any thoughts?
