Where Did Your Birth Come From?

Your birth was the birth of your parents, yet that so the ego is trying to ground itself in an idea of a birth. You see, you want to ground your birth in the big bang, but the big bang is something you learned and invented after your birth. So where did your birth come from? Do you even birth? Or is your birth just a memory that your ego invented to anchor your sense of sanity and existence? If you realize that your birth is just imaginary, then what is this doing here? How did i get here? That gets a little closer to enlightenment.
