Well we would have to, eventually. It would still be long till the Sun gobbles up our planet but if climate change continues, we could end up like Venus. Though it seem the public is not enthusiastic anyway. With the war on science, isolationism and populism becoming more common, funding could get redirected to other stuff.
You won't find an oxygen atmosphere on a planet by chance; oxygen is far too reactive to exist naturally in a free state. You know why water's the most common compound in the universe? Because hydrogen is the most common element, so whenever there's oxygen around - BOOM! Oxygen also reacts with carbon to form carbon oxides, silicon to form rock, and metals to form rust: all of which can be found in varying levels of abundance on other planets, but no free oxygen.
The only reason Earth has oxygen in its atmosphere is because algae and plants are constantly producing it as a waste product, and the only way another planet can have oxygen is if it already has life like ours, which may be inconvenient for colonists.
Also scientist have recently mentioned that planets with liquid water on the surface might be rarer than expected. They were kinda hoping that icy planets would become more habitable as their suns expand but it turns out that is more unlikely. https://phys.org/news/2017-07-planets-hospitable-earth.html
Mathematical nonsense.
There are hundreds of billions of stars in this galaxy alone, with hundreds of billions of galaxies.
Each star has multiple planets.
Eventually, we will find some that support our life.
