While I agree Earth first. But just like most humans you are underestimating our level of risk. There is a very legitimate reason to have a goal of not putting all our eggs in one planet. That's just a much more long term goal than our climate issues, but we shouldn't stop trying to progress our technology for that end.
True, but colonizing other planets is more distant a goal than making our own stable.
I agree that redundancy is a good way to mitigate risk, but there are so many problems between us and successfully colonizing another world that this is basically a pipe dream.
Astronauts experience a lot of health issues.
And of course there's all the problems caused by radiation exposure once you're outside the Earth's magnetic field (Mars doesn't have a global magnetic field). Basically, we can put ourselves in a tin can and venture into space, but the human body evolved in Earth's gravity and radiation profile and it doesn't do well outside of that. At the present you'd have to be suicidal to try to live long-term away from Earth, and I don't think these are problems that we can just engineer our way out of.
None of those problems get solved if you use the enormity of the task to excuse giving up. Everyone working on these projects is well aware of these issues. It does not devalue the work. But do not confuse my support of continuing towards the goal with support for goofballs like Elon Musk.
If we had listened to people like you during the infancy of the US space program we would have deprived the world of a lot of technological progress.
We will not accomplish any of this. Because we don't even care for the biosphere of the planet we already have in the best state of "terrafoming" ever.
Humankind will speedily regress to much lower levels of organisation and technology soon. It's inevitable.
