Try Below Code 
trigger test on Account (after  insert) {
    list<Contact> lstCon = new list<Contact>();
    for(Account Acc: trigger.new){
        Contact con = new Contact ();
        Con.FirstName = 'test';
        Con.AccountId = Acc.Id;
        Con.LastName = Acc.Name;
        lstCon.Add(Con);

i have written the same code but just for extra caution i came here and copy paste it in my dev console but it still showing the same error : "Variable does not exist: FirstName". I have never faced this error, Can you bother to tell what is the problem cause i have write this code many times in past but i never faced this problem.

Please check if the field 'FirstName' exist in the contact object. Also make sure the field api name is 'FirstName'.

Follow My Code. It is very Usefull:- Trigger on after insert, after update, after delete, after undelete on Contact
public class CountContactOnAccount {
    Public Static void countContact(List<Contact> conList){
        List<id> accId = new List<id>();
        for(Contact con : conList){
            if(con.AccountId != Null){
                accId.add(con.accountId);
            }           
        }
        List<Account> accList = new List<Account>();
        for(Account acc : [Select id,(Select id from Contacts) from account Where id IN: accId]){
            acc.NumberofLocations__c = acc.Contacts.size();
            accList.add(acc);
        }
        if(!accList.isEmpty()){
            update accList;
        }
    }
}
