Why did God create the world in this way and not like the other possibilities?

I would like to express some questions and points here regarding why God made this world as it is and not a world where humans could simply fly away at will. So, my main question to be brief is: Why did God create or willed reality in this way? That He allowed gravity in this level and not like other Mars, or why He didn’t allow us to be underwater creatures or flying ones. The thing that I’m struggling about here is the idea that God allowed us to have a choice; free will. Now what I have thought about is this: Do we really have free will if there are things that are naturally impossible for us to choose, therefore limiting our choices? Like you cannot choose between “flying” or “not flying”. You can only “not fly”. So can you really say “well, I still have free will” The answer that I have thought is “well, God has to set up some form of reality or limits. Otherwise, free will without limitations can include illogical conclusions such as existing and not existing at the same time” So okay, God creates a reality for us to live in: why this reality and not other realities? I apologize in advance if you think this is way too simple, lacking or so and so. But I hope you get the point.
