...Humans evolved to live here, on Planet Earth. Not on our own star, or on any other star, and humanity's future is right here where we have an entire planet we were built for... not on a foreign star.
I disagree. No matter how inhospitable, we will go there, and try to live there. My opinion is based on history. People migrated out of Africa, where they had evolved, into Eurpoe and Asia, which had relatively inhospitable climates. More recently, people have chosen to live at the South Pole, which is almost as desolate as the Moon.
