I once put a pair of jeans in the dryer to have them come out buttoned up. I couldn't replicate it in my life time most likely no matter how many loads of laundry I did. It doesn't mean it didn't happen. It was a purely random event.
Now, humans on occasion have purely random events that cause them to do amazing and extraordinary things. I don't believe we understand, grasp, and comprehend the things of this world enough to ever make a judgement on what CAN be done. I think we can perceive what we think is possible based on the body of evidence laid out before us. Beyond that, we just have to wait till someone figures something out.
Try reading about Edward Leedskalnin, and his Coral Castle and tell me he didn't figure something amazing out that the rest of us just don't know.
