The captain of the sun

Everyone died.
The navy ambushed them.
So imagine the Strawhats surprise when they not only wake up 2 years before the start of their journey, but wake up looking at themselves
Will they be able to save the world?

------------
This is my first fic so please give me tips on how to improve
I wanted to write a story based on the idea that not only are the straw hats brought back in time but their past versions of themselves are still around and just trying to put together the pieces of wtf is going on. Have fun and I hope you enjoy!
