If I lived in an alternative universe then a pre-requisite would be looking at Earth and considering what aspects of Earthling example might be applied to life on my alternative universe.

On close observation, I saw the violent crime, theft, white collar crime, greed, avarice, and environmental disruptions resulting from the greed of mankind.

I saw world leaders talking of peace but preparing for war. I saw conflict in every part of the world, people fighting civil, regional and wider world conflicts.

There were small pockets of happiness but Earth was generally shrouded in a black cloud of despair.

From my alternative universe, I determined that I would like it to be an environment that was based on ANYTHING other than the example offered by Earth.
