its about disappearing new branches plus The main itself

Last Try Before solving Problem: shows the line which dont recognition the Mother Branch

four first lines of code

Here is The Code:

First i initialized a repo:

   $ git init

then renamed Master to Mother:

$ git branch -m "Mother"

created a readme.md:

 $ touch "readme.md"

The First error when i tried to create a new branch then, I got caught in it was(exactly is shown in the first image):

 $ git branch Product
    
    fatal: not a valid object name: 'Mother'

after creating several branches by alt:

   $ git checkout -b Product
    
    Switched to a new branch 'Product' 

and commiting the readme.md file..

i tried to switch to The previously created branches but the main question is here:

   $  git checkout Product
    
    error: pathspec 'Product' did not match any file(s) known to git

this even happened for my Root:

$ git checkout Mother

error: pathspec 'Mother' did not match any file(s) known to git

so i recreated those branches again:

  $ git checkout -b Product
    
    Switched to branch 'Product'

The Problem Solved but whats the reason behind it

may you tell me why?

>Solution :

Branches in Git are pointers to existing commits. When you init, your repository has 0 commits, thus you cannot create any branches. Once you have a commit, you can create new branches.
