@davidgasquez well, that's part of us being human. We really are standing on the giant's shoulders, and we have to trust others for the vast majority of things.
Did you personally checked or are able to tell what minerals are in a stone? Are you actually able to build a remote control by scratch, or understand how planets or plants work? I don't, I mainly trust others and there is nothing wrong with it. Actually it's not something you can avoid, IMO
