I assume you believe the Earth has always been here, it has always had this climate which allows us to survive and it always will, nothing will ever change
The exact same argument could obviously apply in the case of those calling for the evacuation of Switzerland to Krakatoa for example.In which case why the double standard regarding the ‘new’ planet home.
Let alone the impossible figures and the equally impossible living conditions involved in sending a manned space craft to the Alpha Centauri system let alone further.In which even if you could make something large enough and fast enough and provide the life support systems and even if you could find the ‘volunteers’ to go you’ll at best end up with a load of home sick mentally traumatised ‘colonists’ before they even touch down on their new ‘home’.On that note there’s no more reason to think that the so called colonisation of space wouldn’t go along similar lines as the colonisation of Australia but with a ‘much’ unhappier ending.
