After Mars map

You have awaken your suit reads 10/7/2045 but you don't remember anything since 2015. The las thing you remeber is a large explosion and your ship and crew taking off without you. Now you are alone, scared, and hungry. You don't know anything about how to grow plants and crops but you do know they require oxygen and your biodome has been destroyed. All you have left is a freezer, the pantry, and some meat from the farm. How will you get back to earth and when will the distress ship come for you?

This is my map entry "After mars" this is my first ever major build and im not that good at it. The only thing I know im slightly good at is command blocks so i added a few minor touches to the map. I hope you like it. Thankyou for looking at my submission.
