We don't know exactly how much time is on Earth, but I'm actually pretty content with jst letting things run its course.. and when humanity is gone, then it's gone. Who knows when that will be or how it will happen, but the idea of colonizing another planet just seems so far-fetched for me. Is it really that plausible? To eventually send like millions of people to Mars? It would take unbelievably long to set up a society on another planet, and I feel like it's just a ton of money spent on something that isn't realistic.
