Wow I never thought of that, shinigami_xero, that the laughter in the end was human children laughing. I hope that is true, because it seems way too depressing to think that all human life ended, and only Nanaki's kind survived, which is what I always thought after seeing the ending. There were references in the game saying how humans kept damaging the planet, and if they kept going they would eventually destroy it- so I assumed after seeing the end that the lifestream ended all the humans lives because they hurt the planet so much. Also, when they show Nanaki and his pups looking at a ruined Midgar, wasn't it like years into the future? If humans still lived on the planet I figured they would've had enough time to rebuild Midgar and live there again. Plus it seemed as if Nanaki was looking at Midgar as if he was remembering his old friends, like they weren't around anymore. I don't know, sorry for writing so much I just felt I had to get my feelings out on the strange ending of FF7.
