If someone lost his money ( bitcoin amount ) then no one can change or Destroy and not able to create again for that return .
If you have better information about bitcoin then surely you will know very well that about 60%+ bitcoin as out of control , Because many people started to work with bitcoin when bitcoin was not valuable at that time but they left Thier work and also many sites get closed and that results into lost of bitcoin in the bitcoin network forever .
And also you can think that if anyone can see what you lost and they will create another for that then I don't think it will remain decentralised thing .
So no chance to recreate bitcoin that you lost , but surely there exists a technology named fork that can create additional new coin with another name ( as happened in fork that results into bitcoin cash , bitcoin gold , bitcoin diamond , bitcoin ab , bitcoin private etc ) .
