Whatever we could do to earth it would still be more hospitable place than Mars. I’m sure we can have bases on any body in the universe, but that’s far from “colonizing”. If we want to live in tunnels or hermetically sealed bases we can do it on earth with much less effort! The only reason to do it on Mars is hedging bets against extinction events. And I find it extremely hard to think you’d find someone interested in going anywhere otherwise. It would be a lot more convenient to re-colonize earth after an extinction event than to colonize anywhere else!
