>I also had nothing to do with picking my ancestors

You are the product of your ancestors. What you're saying is like a tree branch saying "I had nothing to do with picking my tree". A tree branch doesn't exist as an isolated individual from the tree and then get randomly assigned to a tree, it only exists because it was created by the tree.

If the tree hadn't created it, then it wouldn't randomly belong to another tree, it just wouldn't exist at all.
