IDs not available in Before insert. How to uniquely identify the records

Hi, 
In the before insert context, the IDs are not yet assigned to the list. In such scenario, If I need to create a map to uniquely access each record. What is the best way. Cannot depend on the field values.

trigger youtriggerName on yourObject__c(before insert) {
    Integer size = trigger.new.size();
    Map<Integer,yourObject__c> myMap = new Map<Integer,yourObject__c>();
    for(yourObject__c c : trigger.new){
        for(Integer i=0;i<size; i++){
            myMap.put(i,c);
        }
    }
    System.debug(myMap);
}

I Don't think, i need inner for loop fot this 
trigger youtriggerName on yourObject__c(before insert) {
    Integer i= 0;
    Map<Integer,yourObject__c> myMap = new Map<Integer,yourObject__c>();
    for(yourObject__c c : trigger.new){
         
        myMap.put(i,c);
        i++;
    }
    System.debug(myMap);
}
