But but but...Humans are smarter than other forms of life.(on Earth)

The reason we do not have gill's is because we walked on land, tails because we don't hang of branches. We are the most advanced species on the planet and we keep advancing. Our average lifespan is increasing generation on generation.

Our chances of long term survival far outweigh that of any other species. Our ability to travel into space and possibly create colony's is not something another species can hope to achieve. This planet at some point will become inhospitable and humans are the only species with a real chance of survival.
