You have to verify yourself that this is a level that human beings can reach, should they connect with their Creator and ask (beg) to level-up and learn.

My comments over the past few days explain it quite fully.

The "evidence" I would suggest is that the only tool-making animals are some primates and birds, but I'm sure there are others. But that is not abstract thought and thoughful choosing. Their choosing is purely for survival benefit, including their partnering with humans.
