It seems incredibly arrogant and short-sited to assume that humans would be able to somehow survive outside of their original environment. There isn't a grocery list of things we need to bring into space or to another planet. Everything on this planet is interrelated and inseparable in largely unknown ways.
You don't need that much to just survive - food/water, atmosphere, low enough radiation, manageable temperature.
All of these problems can be solved with our current level of technology on Mars. After you establish the base near a water source, you can grow your own food, you can make oxygen, you can mine for whatever elements you need.

On Mars this stuff will die out right away, and to replicate it you will need to create another Earth.Gut bacteria is just a tiny example, there is other stuff like bone problems, vision problems, etc. I am appalled that instead of fixing mess here on earth, the only known planet to support life, we waste brains, time and resources on these idiotic fantasies
Well there's one thing, if we can manage to build a survivable habitat on a planet like Mars--relatively mild as it may be, compared to other space places--surviving on a planet on the verge of some global climate catastrophe is going to seem like a piece of cake ;-)
