we ourselves create our own universe

И Бог шагнул в пустоту. И Он поглядел вокруг и сказал — Я одинок. Сотворю себе мир (Джонсон)
Well, everything what we have is the result of our own decisions + some element of probablilty (white noise or random error).
The problem is that we can't predict the future, we can make only backword estimations and realise (if we have enough information to get that) if we made a right or wrong decision.
