Am an employee of amazon i was involved in an accident drivin home from work will i able to come back to work after missing weeks

No

Yes call the ERC

Call the ERC and talk to a leave of absence personnel and also go to your local HR to provide proof of your accident. Considering the situation and the amount of UPT/PTO you have also for days missed i see no reason for them not accepting your reason.

For sure if you can prove reason for missing...
