Can adoption or even stepparenting really create the same bond as having biological children?

Many people think that adoption is a great alternative to having bio kids but I have my doubts.

1) I am following many adoptees on social media and many seem to believe that adoption is just different than having a bio family. Many also resent being adopted and believe that private adoption is hugely problematic.

2) I have a stepfather who is actually very nice while my bio father is a total shithead. Despite this I still somehow feel emotionally closer to my bio dad.

3) My personal experience has taught me that friends come and go and blood family is more reliable.

Obviously, my experience is not absolute and many might feel differently but my gut feeling is telling me that the family bond you have with your bio kids can't easily be replicated via adoption, stepparenting, having close friends etc.
